String contains an invalid utf-8 sequence. I tried various Lua functions for working with UTF8 strings for example: string.subutf8(string, start[,end]) for i, char in str:nextutf8(orig_pos) string.lenutf8(string), but without success. Can you please someone help? Thanks Jaroslav Hajtmar Here is my minimal example: \def\mymacro#1{\ctxlua{for i=3D1, string.len('#1') do = context(string.sub('#1',i,i)..", ") end}} \starttext %\mymacro{=B9=EC=F8=EC=BE=F8=FD=E8=F8=E8=BE=E1=FD=E8=FD} % Here is a problem \mymacro{asdfghjklqwertt} % Here is all OK \stoptext ___________________________________________________________________________= ________ If your question is of interest to others as well, please add an entry to t= he Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-cont= ext webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________= ________
