text recognition errors with some fonts

Our app has a default set to use Tahoma for certain display elements to guarantee that japanese and chinese characters are properly rendered on the app.

When I use sikuli on Windows (rc2) text recognition with the font set to Tahoma (11).
It fails to find certain text, mainly letter combinations involving an 'l'.

Examples include: ClearBits, and Playlists. I assume it's because the character spacing in so close together.

To reproduce:
 1. Launch Miro (nightly or beta build from http://nightlies.pculture.org)
 2. Launch Sikuli IDE
 3. Try find("ClearBits") or click("Playlists")
 Result: recognition fails - even if searching in a very limited region.
 4 Try find("Bits") or 'lists'
 Result: recognition successful.

Additional info - I had similar text recognition issues using the default Ubuntu font on linux maverick, however I was able to workaround by changing the system font preferences to something more machine readable.
