You are missing something (the manual is unclear). The correct syntax is: \prehyphenchar<language number><optional eq><char number> Best wishes, Taco

Sorry, I am an idiot. I just checked the source and it says: \prehyphenchar<char number> The idea was that this matches \patterns and \hyphenation: neither accepts a language number or an equals. (but the manual is still unclear, I had that right at least)

Hmm ... I would more expect it to match TeX's \hyphenchar (to match \patterns, the syntax IMO would have to be \prehyphenchar "{"<char number>"}"). But maybe I was confused by "All languages start out with \prehyphenchar=`\- and \posthyphenchar=0". OTOH, it is an integer parameter, so I might have thought that there would be an optional equals sign just as with TeX's other integer parameters (even though this one is not global, but language-specific).

Agreed. I will add an optional equals sign in the next release. Best wishes, Taco

this works ok here so maybe your ` or \- is messed up ----------------------------------------------------------------- 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 -----------------------------------------------------------------
