- Ensure that Preferences > Style > Font Engine is set to "DirectWrite (Standard)".
- Type in a character from the Telugu Unicode block.
- Type in some non-alphabetic characters after the Telugu character.
Expected Behavior
- Non-alphabetic characters are formatted in the same manner as the rest of the text, like in this edited image.
Actual Behavior
- Non-alphabetic characters all show up black and (I believe?) in a different font as shown in this image.
Workaround
- This issue does not occur when using the FreeType Font Engine instead of DirectWrite as shown here.
Additional Notes
- The character ౷ is in the Telugu Unicode block, but doesn't trigger this bug on my end, as seen here.
- Not every non-alphabetic character will turn black either, but I haven't tracked down precisely which specific characters are affected by this bug and which aren't.
- It's also very likely that more characters could instigate this bug than just the Telugu Unicode block, but I haven't tested blocks outside of that either.

Thank you for the very detailed report. This must be a bug in Qt. I will see if there's a fix in any of the newer Qt versions.
