currently a character node in tex has the only attribute, ie the associated font. I m wondering whether it makes sense to replace this attribute (font) by a pointer to some data structure representing a set of attributes. This way we can add further attributes of a character without messing up around the sources. Such attributes can be: font, color, location in tex sources, next bytes of a utf8 sequence etc. How to you guys see it?
this is indeed a much wanted feature although i don't know what you mean with utf 8 here since at the char node that has already been reslvbed
maybe one could keep character storage in (variable length) UTF format throughout? Actually what would happen if the control sequence names would be stored without input conversion in the pool with their original UTF format? The hash would still work with UTF codes. Problems are e. g. how to replace the eqtb area with the first 256 characters? Maybe also use there a multi-byte sequence with a "single character" attribute?
but in that case we should use unicode slots a la xetex or aleph ... somethign we need to do anyway when pdftex moves open type Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
