Are you sure the glyph is contained in the True Type you are using?

Could you attach here a XAML with just a TextBlock reproducing the error?

Hi jsantos,
I using font Arial Unicode MS, could you try with textbox NoWrapText

I found another bug, it does not support single character Korean (some times) . Let type "g" + space.

Could you create a single XAML with just one TextBlock (not TextBox) and with the characters that are giving trouble to you? That way it is easier to debug for us. if possible, please also include the font (just in a single .zip and upload it to google drive or something similar because we don't allow big attachments here)

Thanks!

Hi jsantos,
It not related to display Korean, the bug is when we typing the Korean not correctly
For debug, could you install Korean keyboard IME

-> Backspace few time.
-> Type gksrmf +space
-> Expect 한글
--> Result 글

Thank you

Thanks for your feedback, so there is no problem when you display those characters in a textblock, the issue is only happening in the textblock, right?
It seems to be a IME issue then (as you perfectly pointed out)

The problem is Typing Korean in TextBox
Thank you.
