When fonts in the Eagle interface appear abnormal (thin or unclear), whether Chinese or English fonts, it's usually caused by system default fonts being deleted or overwritten by abnormal fonts with the same name. This article will guide you on how to resolve this issue.

Resolving Chinese Font Display Issues

Open the system's "Font Book" application
Check if system default fonts exist:

Check Microsoft YaHei font

Check PingFang font
Disable or remove manually installed fonts with the same name
Restart Eagle software

Resolving English Font Display Issues

Restore changed font settings in Windows:

Go to Control Panel > Fonts > Font Settings
Click "Restore default font settings"

Check if the following system preset fonts are missing (reinstall if missing):

SF Pro Text
Helvetica Neue

Important Notes

Font display issues are usually related to system fonts, not Eagle software itself
It's recommended not to randomly delete or replace system default fonts
If the above methods cannot resolve the issue, you may need to consider reinstalling system fonts
