Double byte character support in the Editor control?

Yes, SyntaxEditor does support non-english languages. It is IME capable and supports double-byte characters. Just make sure SyntaxEditor.UnicodeEnabled is set to true if you want to support those types of extended characters.

User sent me a screenshot and it looks like the problem is not with the Editor control - but if someone could give me a quick confirmation that non-english characters are supported fine that'd be much appreciated.

Thanks! We love the control, btw. Cool stuff! Want to check out our fun implementation around it? http://www.ms-inc.net/kpl.aspx. KPL for Kid's Programming Language. :)

If you look at the Unicode Support topic in the documentation that has a screenshot of Chinese characters in SyntaxEditor with UnicodeEnabled.

Out of curiosity, why would you not want to enable Unicode support? Is there any benefit to leaving Unicode disabled or potential issues with enabled Unicode? Thanks!

Yes due to the way Microsoft implemented GDI+ text drawing, it's impossible to accurately paint runs of text. Things get squooshed together if you try. This is a well documented issue. Therefore, for variable width fonts and for Unicode fonts, we have to render text character by character. So there is a slight performance hit since painting isn't quite as optimized in that case.

Thanks for the clarification, and I hate that GDI+ issue. Do you happen to know if this issue has been resolved for .NET 2.0 or is it even part of the .NET package?

I still have to see if there is a workaround in 2.0, however I think I saw that some of their controls like Labels have some new property that says use GDI-like drawing or something like that.
