OS X Quicklook Font – Preview international characters
To Show international characters in OS X (tested on Leopard, Snow Leopard, Lion) Quuicklook Font Preview edit file:
/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/CoreText.framework/Versions/A/Resources/SampleSupport.plist
Add characters you want to show in corresponing key.
How to:
1. To open folder paste
"/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/CoreText.framework/Versions/A/Resources"
in Go to Folder menu (Menu/Go/Got To Folder…) (Command-Shift-G by default)
2. open file “SampleSupport.plist” in any unicode text editor (i prefer Smultron).
3. edit corresponding keys
For me:
<key>en</key>
<string>ABCDEFGHIJKLM
NOPQRSTUVWXYZ
abcdefghijklm
nopqrstuvwxyz
1234567890
ĀČĒĢĪĶĻŅŖŠŪŽ
āčēģīķļņŗšūž
ЙЦУКЕНГШЩЗФЫВА
йцукенгшщзфыва
</string>
4. save
