I use the pipe character quite often in my glossaries because it is quite useful for German, which is an inflecting language.
Would it hurt much to copy the glossary, reverse it, and delete all pipe characters at the target side? And wouldn't that be a hell of a lot simpler that "hiding" them? If possible at all?
Come to think of it, depending upon how you set up your glossary, this may not be possible. And I thought I covered ALL disadvantages/stupidities of tab del glossaries...
I am going to look into the pipe display issue in the reversed language-pair direction as soon as possible.
The issue with the visible pipes in the reversed language pair of glossaries has been fixed.
