How can I get a german spell checker ?
HelpStudio 3 & HelpStudio 2011 both support using non-english spelling dictionaries (including German). I have outlined the process to set these dictionaries below:
HelpStudio 3
You can change the primary locale dictionary to German by going to Tools > Options > Spell Check Dictionaries, then change the Primary dictionary to German (you can download HelpStudio 3 dictionary packs here: http://www.innovasys.com/download/updates.aspx)
You can also change the spell check dictionary per secondary locale in the locale editor.
HelpStudio 2011
You can change the primary locale dictionary by going to Tools > Options > Spelling Options > select (default) > change the Main Dictionary to German (HelpStudio 2011 ships with secondary language dictionaries that can be found here: \program files\innovasys\helpstudio2011\configuration\spelling\)
You can add new languages here which will then be used by the matching locale in your project.
