SyntaxEdit Hindi character issue

Albert Wiersch

A customer reported this issue to me with SyntaxEdit handling Hindi characters "funny".

Please see the attached example document. Load as UTF-8 in SyntaxEdit and then pass the cursor through the Hindi (I think) characters using the cursor keys to see the "funny stuff".

Can you provide a fix? Thanks.

NOTE: System is not letting me upload the file. It gets stuck on "Uploading...", so please get file here: https://www.htmlvalidator.com/test/HindiTest.html

OK, thanks for taking a look. I hope it can be fixed.

Hi,

The issue happens because thouse Unicode characters has different width in pixels when measured separately (character by character) and when measured as a whole text string. This, unfortunately, can't be fixed; its not possible to implement fully correct Unicode support in our code editor.

Btw, Delphi code editor has same issues; not exactly same behavior, but also, very strange.

Eugene,

OK, thanks. I'll inform the customer.

Oh, do you know if changing to a certain font might fix this?

I think - no. Its a complex case of Unicode, when, for example, several characters (codepoints) can be drawn as a single letter; or the character shape (and width) can depend of surrounding characters, ect.
