Support note (2026-09-05): this README is supplementary. The support record is the only capability authority; it separates native compatibility evidence from Wasm policy and smoke evidence. Options mentioned here but not promoted in that record are not compatibility guarantees.
Translate, squeeze, or delete bytes read from stdin:
Options: -d delete SET1 bytes, -s squeeze repeats, and -c/-Ccomplement SET1. -t truncates SET1 to SET2's length. Sets support escapes(\n, \t, \123), byteranges, C-locale character and equivalence classes, and [CHAR*COUNT] orSET2-filling [CHAR*] repetition. Operates on raw bytes under the fixedLC_ALL=C profile; locale data beyond that profile is intentionally notconsulted.
