Hi there! I try to typeset a roleplaying character sheet as PDF form; it contains a table of skills, each line is a \SkillField after this def: \def\SkillField#1#2{\bTR\bTD #1\hfill (#2) \eTD \bTD \definefield[#1][line][SkillSetup][#2]\field[#3]\eTD\eTR} e.g. \SkillField{Climbing}{+8} becomes a table line like: Climbing (+8) [+8] Now there are a lot of skills that contain e.g. umlauts, so that \definefield[#1] fails. I don't like to introduce a third parameter. Is there a possibility to strip all invalid chars from a string, so that \SkillField{Erzählen}{0} can define a field named "Erzaehlen" or "Erzhlen" or "Erzahlen"? (Sorry, I can't program in TeX.) If this is not possible, I'll try an optional parameter. Grüßlis vom Hraban! --- http://www.fiee.net/texnique/ http://contextgarden.net
