+    note "Note 1 (MARC-8): within a strictly MARC-8 environment the
+    double underscore may be applied to a base character n following

+    the advantage of extended Latin."
+    note "Note 2: a single prime (ʹ, U+02B9) is inserted between two
+    letters representing two distinct consonantal sounds when the

+    following the practice of the Journal of Coptic Studies, with the
+    exception of the iaude (ⲓ) and ua (ⲩ) diaereses, which carry Ï/ï

+    J [Ch]) are intended solely for preparing references from West
+    Armenian forms and are not encoded here — the primary rendering is
+    encoded per row. The table covers the complete letter inventory
+    (including the ու digraph, the Եւ/Եվ/և forms), the Note 3 soft-sign
+    (prime) combinations, the punctuation transcription rules, and the
+    letter-numeral table. The aspiration mark is U+02BB (ʻ); the soft
+    sign is U+02B9 (ʹ).
+  }
+
+  notes {
+    note "Note 2 (position-dependent, not encodable as a character rule):
+    the value Y (y) of ը/ը and Յ/յ applies only when the letter is in
+    initial position of a name and followed by a vowel, in Classical
+    orthography. The default value encoded here for ը/ը is Ě/ě (the
+    letter's general value per the table); Յ/յ defaults to Y/y."
+    note "Note 4 (position-dependent, not encodable): Յ/յ carries Ḥ/ḥ
+    when in initial position of a word or of a stem in a compound, in
+    Classical orthography. The general value Y/y is encoded."
+    note "Note 6: the prime is placed between e and v for a closed set
+    of exception words written with եվ/եւ in the lower case (dpreʹvankʻ,
+    ageʹvaz, Kʻareʹvankʻ, hogeʹvarkʻ, hogeʹvichak, oskeʹvaz, osokeʹvars,
+    ugheʹvchar, gereʹvarel, gineʹvachaṛ, gineʹvarpet, dapʻneʹvard,
+    kareʹver); word-initially eʹv, except ևեթ evetʻ and ևս evs. All-caps
+    ԵՎ is transliterated ev without the prime (Երևան/ԵՐԵՎԱΝ Erevan).
+    The map encodes the table's plain row values (Եւ Ew, եւ ew,
+    Եվ/եվ Ev/ev); the word-dependent prime cannot be encoded."
+    note "և (ech-yiwn ligature) is encoded to ev, per the romanized
+    examples in the table itself (ev ayl erker; ev imě; evetʻ; evs).
+    Note 5 hedges that in Classical orthography the ew value sometimes
+    appears written with this ligature. The all-caps digraph spellings
+    ՈՒ and ԵՒ (the yiwn has no separate capital) carry the values of
+    Ու and Եւ."
+    note "The Armenian question mark (՞) and exclamation mark (՜) are
+    transcribed at the END of the sentence in the Latin transcription
+    regardless of their position on the Armenian word (they sit over a
+    vowel), so their repositioning cannot be expressed as a character
+    rule and they are not encoded. The shesht (՛) is not transcribed
+    (encoded to empty). The verjaket (։) becomes a period. Angle
+    brackets «» used as quotation marks become “”."
+    note "The letter-numeral table is encoded as letter followed by the
+    one-dot leader (U+2024) exactly as printed in the source. In real
+    texts the numeral mark may also appear as other dot punctuation,
+    which this map romanizes as the punctuation output of that mark."

+  description {    ALA-LC Manchu Romanization Table, 2012 version (no earlier
+    versions). The printed table gives each letter in its isolated,
+    initial, medial and final forms; Manchu is a cursive script and all
+    positional forms of a letter share one Unicode codepoint, so each
+    row encodes one rule. The before-vowel variant letters of the
+    printed table are distinct letters of the script and carry distinct
+    codepoints: k (1) before a, o, and ū / k (2) before e, i, and u;
+    likewise g (1)/(2), h (1)/(2), t (1)/(2), d (1)/(2), and f (3)
+    before a and e only versus f. The letters and digraphs used in
+    foreign words (kʻ, gʻ, hʻ before a and o; ts, dz, ž, sy, cy, jy per
+    Chinese pinyin values) are shown in the table in isolated form.
+    The Unicode correspondence follows the standard Mongolian block
+    model: shared Mongolian letters, the Sibe letterforms that coincide
+    with the Manchu forms, and the five Manchu-specific codepoints
+    (Manchu I, KA, RA, FA, ZHA); the three foreign-letter forms kʻ gʻ
+    hʻ correspond to the Todo KA/GAA/HAA codepoints, and ts, dz, ž to
+    the Sibe TSA/ZA/ZHA codepoints.
+  }

+    note "Positional variant letters and their codepoints: k (1) ᡴ,
+    k (2) ᠺ, g (1) ᠭ, g (2) ᡤ, h (1) ᠬ, h (2) ᡥ, t (1) ᡨ, t (2) ᠲ,

+    u ᡠ, ū ᡡ. The vowels e, u, ū and the consonants g (2), h (2),
+    p, š, t (1), d (1) use the codepoints of the Sibe letters whose
+    forms coincide with the Manchu letterforms (Unicode Mongolian
+    block, Manchu section)."
+    note "The foreign-word digraphs sy, cy, jy (Chinese pinyin si, chi,
+    zhi) are written with the s/c/j letter followed by the i letter.
+    cy (ᠴᡳ) and jy (ᠵᡳ) are encoded as digraph rules: the letters c
+    and j do not occur before i in native Manchu. sy (ᠰᡳ) is not
+    encoded as a digraph because the same sequence spells the native
+    word si (you); the pinyin value sy applies only to Chinese loan
+    syllables and cannot be distinguished at the character level."
+    note "The diphthongs listed in the table (ai, ei, ui, oi, ūi) are
+    sequences of the vowel letters and romanize automatically; ūi is
+    written with the vowel letters ū + i."
+    note "Case endings separated from the word are attached with a
+    hyphen (e.g. gurun-i, gisun-i); the hyphen is retained as written."
+    note "Old Manchu (tongki fuka akū hergen) is romanized as if it
+    had the added diacritics (tongki fuka sindaha hergen), i.e. as the
+    corresponding modern letter values."
+    note "Capitalization: all proper nouns (personal names, corporate
+    names, ethnonyms, geographical names, names of dynasties and
+    reigns, e.g. Abkai Wehiyehe) are capitalized; the first word of the
+    title of a book, periodical, or series is capitalized."
+    note "Sources cited by the table: Norman, J. A concise
+    Manchu-English lexicon (Seattle: University of Washington Press,
+    c1978); Li, G.R. Manchu: a textbook for reading documents
+    (Honolulu: University of Hawaiʻi Press, c2000), which follows the

+    romanization of the Vai syllabary as scoped by the table: 239
+    syllable characters across the e, i, a, o, u, ɔ and ɛ vowel
+    series (including the nasalized syllables and the ŋã, kpã, gbɔ̃,
+    kpɛ̃, gɛ̃, ŋgɛ̃, ŋɔ̃, ŋɛ̃ forms) plus the syllabic nasal ꘋ (ŋ).
+    Nasalized Latin vowels are normalized to the precomposed tilded
+    letters (ẽ ĩ ã õ ũ) where they exist and to the combining tilde
+    for ɔ̃ and ɛ̃. The extended Latin letters ɓ ɗ ɛ ŋ ɲ ɔ follow the
+    table's Note 1 (Unicode standard usage approved by NDMSO, 2007).
+  }
+
+  notes {
+    note "Note 1 (MARC-8): within a strictly MARC-8 environment the
+    double underscore may be applied to a base character following
+    LCRI 1.0E for ɓ ɗ ɛ ŋ ɲ ɔ (b̳ d̳ e̳ n̳ n̳ o̳); the ambiguity of n̳
+    illustrates the advantage of extended Latin, long-standing in the
+    Vai transcription tradition."
+    note "Note 2 of the table excludes four categories of rarely used
+    Vai characters: archaic logograms, Momolu Massaquoi's innovations
+    (c. 1911), digits, and punctuation. In addition, the printed
+    syllable grid does not include the twenty-eight syllable
+    characters of the th, dh, sh and zh series of the Unicode Vai
+    block (U+A50F U+A511 U+A517 U+A519 and the other twenty-four
+    members); this omission is the source table's, and is recorded
+    here so it is not mistaken for a transcription gap."
+    note "The syllabic lengthener ꘌ is described in the table as
+    repeating the preceding vowel; it is an instruction rather than a
+    romanization value, so it carries no character rule."
+    note "The syllables printed che chi cha cho chu chɔ chɛ correspond to
+    the ch romanization of the table; the table uses ch rather than c
+    before i and e."

+    CC:AAM 2012-01-22 (no version year printed on the document; the
+    approval date is from the PDF metadata). The table follows, with
+    minimal exceptions, the romanization method used by the Institut
+    Royal de la Culture Amazighe (IRCAM) for texts published in the
+    Central Atlas Tamazight and Standard Tamazight languages of
+    Morocco, using neo-Tifinagh script. Characters needed to support
+    the Tachelhit and Tarifit languages have also been included, so
+    the scope covers all living Moroccan Tamazight languages in
+    neo-Tifinagh. Forty-two letter rules plus the labialized digraphs
+    and the labialization mark (tamatart). The spirant letters romanize
+    with a macron below (ḇ ḡ ḏ ṯ, U+0331); the emphatic letters with a
+    dot below (ḍ ḥ ṛ ṣ ṭ ẓ); the Tachelhit emphatic d with both marks.

+    Aglyas if applying LCRI 1.0E / LCPS 1.4 (Note 1: extended Latin
+    characters are used in the standard orthography; apply LCRI 1.0E /
+    LCPS 1.4 as needed). The initial capital in the example is proper-
+    noun capitalization, not a script property; the map yields the
+    mechanical aɣlyas."
+    note "Note 2: the Tifinagh modifier letter labialization mark
+    (tamatart, ⵯ) romanizes as the superscript degree sign (°); the
+    labialized digraphs ⴳⵯ and ⴽⵯ carry it as g° and k°."
