// write-receipt.md: a write_admitted messageId is valid iff it holds a Unicode letter (\p{L}) or number (\p{N}) and no
// Default_Ignorable_Code_Point, compared raw (never trimmed). std has `char::is_numeric` (N) but no letter category
// (`is_alphabetic` is the Alphabetic property, which also takes combining marks), and no Default_Ignorable, so both tables
// are embedded: DerivedCoreProperties.txt ranges, Unicode 16.0 (unchanged since 15.1), and the general category L ranges of
// Unicode 15.1 (U+0378 is unassigned in every version, so it is refused either way). The Kotlin, Python and C# decoders embed
// the same Default_Ignorable ranges and take L/N from their platform; TypeScript uses its regex engine's tables.
// Invalid UTF-8 never reaches this check: the MessagePack str decode refuses it.
