- SpecVersion is 0.10: the version command, the catalogue test and the
spec field of every test data file name spec v0.10. The regenerated
test data change in that field only.
- All lists ERR_HEAD_INVALID, last, as section 69 of the spec does.
- The tests of the path rules and of format 3 held literal invisible
and combining characters (ZWJ, VS16, U+202E, soft hyphen, the Kelvin
sign and others), which an editor could normalize or hide; they are
Go escapes now, with the same values.

internal/pathrule checks the paths and the texts of a format 3 head
(spec 29.5, 29.6) with its own tables, never with the Unicode functions
of the platform, whose version changes with each runtime.
- gen reads the 19 pinned data files (UnicodeData, DerivedCoreProperties,
CaseFolding and emoji-variation-sequences of Unicode 18.0.0, and the
15 WindowsBestFit tables), checks their SHA-256 and writes tables.go:
assigned code points, Default_Ignorable_Code_Point, full canonical
decompositions and combining classes, C and F folding, the bases of
the emoji variation sequences, and the non-ASCII code points each
code page maps to ASCII. The data files stay out of git, in .cache.
- NFD, Fold and the key of R7; CheckPath with R2 to R6c and R10,
CheckTree with R7 and then R9, and CheckComment and CheckAuthor with
the invisible-character rule. Errors name the rule and never echo the
creator's text, so that another implementation can match them.
- The canonical text of the tables has a SHA-256, TablesDigest, which
the tests recompute and a TypeScript implementation will share.
- Checked against golang.org/x/text (Unicode 15.0.0) outside this
module: NFD matches on every code point both know, and folding only
differs on the 86 Cherokee letters that CaseFolding.txt folds to upper
case, as these tables do.
- The spec pins the SHA-256 of the 19 files in 29.5.1.
