Open smurfix opened 2 years ago

Describe the bug Liberation Serif: U plus Combining Ogonek plus Combining Tilde places the tilde to the right of the u, not above it.

To Reproduce Copy+paste these three characters:

ų̃

Expected behavior Change font to Liberation Sans, observe correct placement

Screenshots

(The X has been added to demonstrate that the tilde is misplaced but zero-width.)

Desktop

OS/Distro and Version: Debian Testing
Liberation-Fonts Version: 2.1.5
Application Name & Version: observed in LibreOffice 7.4.1.2 but reproducible elsewhere

@smurfix Out of curiosity, what language is this combination used for? That character is not in Unicode (that I could find). So I am curious. Is the tilde used as a tone mark? Or ?

Note: I did confirm the issue, and do not know the fix as the font looks OK (anchors, etc.), but obviously does not operate as expected. I am just another user not the font developer.

You need that e.g. for phonetics and linguistics. My stepdaughter's a student of the latter and managed to find this bug as she prepared a paper. We tried a bunch of random fixes until I found the "just switch to a different font" band-aid. She was not amused.
