I'm not sure without seeing the whole patch, but the un-commented line 1283
Code:
- ReplaceString: {Offset: 15, Find: "%1px", Replace: "32px", MustMatchLength: yes}
should be indented with 2 spaces before the first hyphen.
If that's what you already have and it's still not working then please post the whole contents of your version of patch
Dictionary text font-family/font-size/line-height. Wrap it in CODE tags so that the forum monospace font will display spaces more easily. It's quite a long patch so you'd better wrap it in SPOILER tags, too.
