Assistant renders uppercase Ç as C

**Describe the bug**
Uppercase C with cedilla (Ç) is missing the cedilla in Assistant, making it indistinguishable from uppercase C. Lowercase ç renders correctly.

**To reproduce**
Type anything with an uppercase Ç in Assistant, e.g. https://fonts.google.com/specimen/Assistant?preview.text=%C3%87ok%20%C3%A7ay%20i%C3%A7tim

**Expected behavior**
The above text should render as "**Ç**ok çay içtim", not "**C**ok çay içtim".

**Additional context**
Applies to all weights. Tested on macOS, Windows and Android, using Firefox and Chrome, but it seems to apply across environments.
