(BODY for TO_LOOP): Accept 0x7f. Increment outptr as needed. 2000-07-30 Bruno Haible <haible@clisp.cons.org> * iconvdata/johab.c (BODY for TO_LOOP): After calling ucs4_to_ksc5601_sym, fix the conversion to JOHAB. 2000-07-30 Bruno Haible <haible@clisp.cons.org> * iconvdata/t.61.c (to_ucs4): Change values of 0xa4, 0a6, 0xa8, 0xb4, 0xb8. (from_ucs4): Change values of U+00A4, U+00BB, U+00ED. 2000-07-30 Bruno Haible <haible@clisp.cons.org> * iconvdata/macintosh.c (HAS_HOLES): Set to 1. 2000-07-30 Bruno Haible <haible@clisp.cons.org> * iconvdata/iso_6937.c (to_ucs4): Change values of 0x24 and 0xb4.

(BODY of TO_LOOP): Remove mapping from U+02DC to 0x0020. 2000-07-30 Bruno Haible <haible@clisp.cons.org> * iconvdata/ansi_x3.110.c (from_ucs4): Change entry for 0xed. (BODY for TO_LOOP): Map U+2122, U+2126, not U+2022, U+2026. 2000-07-30 Bruno Haible <haible@clisp.cons.org> * iconvdata/Makefile (gen-8bit-gap-modules): Remove isiri-3342. * iconvdata/isiri-3342.h: New file. * iconvdata/isiri-3342.c (HAS_HOLES): Avoid gaps >= 0xe0, but don't treat 0x80 as a gap. 2000-07-30 Bruno Haible <haible@clisp.cons.org> * string/strxfrm.c (encoding_mask, encoding_byte): Remove.
