An initial byte \xFF will ask for 7 continuation bytes, and then the
shift by (count * 5) will try to shift 35 bits.

- New macro l_strcoll to ease changing 'strcoll' to something else.
- MAXINDEXRK==1 in 'ltests.h' is enough to run test 'code.lua'.
- Removed unused '#include' in 'lutf8lib.c'.

Wrong utf-8 character may have no continuation bytes.

No warnings for standard numerical types. Still pending alternative
numerical types.
llimits.h being used by all Lua code2024-06-20T17:46:06+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-06-20T17:46:06+00:00urn:sha1:a08d82eb132bfd9db5b91e0d5ebcb81d7b26dcd0
The definitions in llimits.h are useful not only for the core. That
header only defines types and '#define's, so libs and core still do
not share any real code/data.
utf8.offset returns also final position of character2024-05-27T14:29:39+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-05-27T14:29:39+00:00urn:sha1:814213b65fa4ab2b1a7216d06f68a6f3df89efcd
'utf8.offset' returns two values: the initial and the final position
of the given character.
