The CPA package's general-journal.iif now holds every posted entry through as_of (closing entries left out, D-36), written as plain ASCII with CR LF, DOCNUM the entry id, QuickBooks Desktop's field limits and subaccount types honoured, and every character written differently listed in the export's warnings and the README (grouped by substitution, TINs masked). The 1099 worksheet stops at as_of too. PDFs print CJK, Arabic, Hebrew, Thai and Devanagari (Noto fallbacks, OFL), and so does the viewer. has_full_tin reads Unicode separators.

# Unicode character properties: how a TIN can be written
|
|
|
|
Governs `ledger_core::parties::has_full_tin` (rules.md B-26): which
|
|
characters separate a TIN's digits, and which are invisible between them.

## Compatibility decompositions (UnicodeData.txt)
|
|
Derived 2026-10-20 with Python's `unicodedata` (Unicode 16.0.0; these
|
|
mappings are unchanged in 17.0): the characters past ASCII whose NFKC
|
|
form is one of the ASCII separators.
|
|
|
|
- `' '`: U+00A0, U+2000..U+200A, U+202F, U+205F, U+3000 (all Zs).
|
|
- `'-'`: U+FE63, U+FF0D (both Dash).
|
|
- `'.'`: U+2024 ONE DOT LEADER, U+FE52 SMALL FULL STOP, U+FF0E FULLWIDTH
|
|
FULL STOP.
|
|
- `'/'`: U+FF0F FULLWIDTH SOLIDUS.
|
|
- `'_'`: U+FE33, U+FE34, U+FE4D..U+FE4F, U+FF3F FULLWIDTH LOW LINE.

## How the books read them (rules.md B-26)
|
|
|
|
A TIN is nine numerals (any script's: `char::is_numeric`) with at most
|
|
three separators between neighbors. In ASCII the separators are exactly
|
|
the space, hyphen, dot, slash and underscore (a tab or line break is
|
|
not one). Past ASCII they are every Zs space, every Dash character, and
|
|
the compatibility forms of the dot, slash and underscore above; the line
|
|
and paragraph separators and NEL are line breaks, as in ASCII, and end a
|
|
run. Default-ignorable characters are invisible, so any number of them
|
|
may sit between two digits without counting toward the three.
