FAQ: Answers to Frequent Questions About Changing Font to Redmi 9C

Can I change the font in a particular application (for example, in Telegram or Chrome)?
Most of the time, no. Apps use their own fonts, ignoring system settings. Except for some launchers (like Nova Launcher) that allow you to change the font for app names. Telegram or Chrome will have to look for modified versions (like Telegram X with custom themes).
Why did my custom font disappear after the MIUI update?
MIUI updates often reset custom fonts, especially if they were installed through ADB or third-party apps. To avoid this, back up /system/fonts/ (if there is root) or save the font file to your PC before upgrading.
Is it safe to install fonts from unknown sources?
No. Fonts in.ttf or.otf can contain malicious code, especially if downloaded from dubious sites: πŸ”— Fontsquirrel (free fonts for commercial use). πŸ”— DaFont (check the license before downloading). πŸ”— Official Xiaomi Theme Store (in Themes app) Check files via VirusTotal before installing.
Can I change the size of the font without changing the style?
Yes, and it's a lot easier. Go to Settings β†’ Screen β†’ Text Size and Move the Slider. You can also include Enlarged Font in Special Features if the standard size is too small. Note: changing the font size does not affect style (type).
Why do some characters appear in squares after changing the font?

Solutions: Set a font with full Unicode support (e.g., Noto Sans or Roboto); Return the standard MiSans font that covers most characters; Use applications like iFont where you can select the font with the desired characters.
