This repository vendors the complete Unicode Character Database 17.0.0 under UCD/ and generates NSS-compatible BMP case mapping tables under TAB/. The generated symbols are intended for MARS-NWE libnwcore:

NSSUniToLower[65536]
NSSUniToUpper[65536]

The generated tables are based on Unicode UCD data, not on Novell NSS shared/sdk/unitables/*.tab files. The Novell files may be used only as shape or compatibility references in the MARS-NWE work tree.

scripts/gen_unicode_tables.py \
  --ucd-dir UCD \
  --output TAB/unicodeTables.c \
  --unicode-version 17.0.0

The NSS table ABI is unicode_t[65536], so the generator emits only simple single-code-point BMP mappings from UnicodeData.txt. Full, multi-code-point, and locale-sensitive mappings from SpecialCasing.txt cannot be represented in these arrays and are intentionally not emitted.
