I am using TextMeshPro to show Kannada language in Unity and there is a problem with ZWNJ character (Unicode: U+200C). It shows up as a vertical line in the text. Example image: 1
I have tested with multiple Unicode and Non-Unicode fonts but I get the same result.
The expected text is: ಕೋರ್ಸ್ಗಳಿಗೆ ಪ್ರವೇಶ
The string that is causing the problem seems to be near the character 
However I do not know Kannada and have no idea how it is structured. It seems like the ZWNJ character can determine the shape of not only the previous character but a series of characters in a word.
That being said, I can edit the font and remove the ZWNJ character so that it won't show up but it will obviously change the text and I that's not what I intend to do.
I have installed a Unity plugin (Indian Font Corrector with support for Kannada) which fixed a few issues of Kannada text but this one particular issue still persists.
Based on what I know so far: Unity doesn't support GSUB to substitute glyphs in font tables for languages such as Kannada, therefore it cannot replace the right characters. For that to work, either a magic update of TextMeshPro or Unity is required, (which is not the case as of today) or, a special font for Kannada is required (which I would apreciate if you know any).
If you have any experience integrating Kannada language in Unity I would love to know how you managed to do that. Thanks in advance.
