Customize Your Code Font

Brackets doesn't officially support a preference for changing the code editor font. But here's a quick hack you can use to work around issues like lack of Russian/Cyrillic support:

• Locate the installed Brackets source:
  • On Mac, right-click Brackets and choose Show Package Contents, then expand the "Contents" folder.
  • On Windows, navigate to your install folder (usually C:\Program Files (x86)\Brackets).
• Edit the file www/styles/brackets_theme_default.less
  • On Windows, due to UAC, you may need to copy this file to another location, edit it, then copy it back.
• Find the .code-font() rule and change the font-family as needed.
• Restart Brackets

Note: when you update Brackets, these changes will be lost and you'll have to repeat these steps. For a more permanent solution, you can write a Brackets extension that loads a stylesheet to override the appropriate font styles.
