Issue #2034 has been updated by Run Paint Run Run. > Adding Unicode sensitive functions to String may be accepted. > For example if the library is loaded, String#unicode_to_i is available. Do you like that API? It feels clumsy to me. Users will have to change their code just to handle Unicode strings, when Ruby could make the determination automatically. > Matz said Ruby's core methods are ASCII sensitive, are't Unicode. > So exist methods won't change. :-( FWIW, Python uses http://hg.python.org/cpython/file/a31c1b2f4ceb/Tools/unicode/makeunicodedata.py to make the C header files, e.g. http://hg.python.org/cpython/file/a31c1b2f4ceb/Modules/unicodedata_db.h and http://hg.python.org/cpython/file/a31c1b2f4ceb/Modules/unicodename_db.h then http://hg.python.org/cpython/file/a31c1b2f4ceb/Modules/unicodedata.c as the API. IOW, a generalised approach of the Onigurma patch. It would take me a while, but if Martin doesn't have the time, I may be able to produce something along those lines, albeit without the clever optimisations initially. ---------------------------------------- http://redmine.ruby-lang.org/issues/show/2034 ---------------------------------------- http://redmine.ruby-lang.org
