font bug screen shot

See attached screenshot for example. This is running a clean install on a retina MacBook Pro. I ran all uninstall scripts and reinstalled from scratch but the fonts still show up as symbols.

We have checked and not able to reproduce the problem. Could you please provide us the test steps you followed along with the Primary Language and region of your system. 

Also can you please add the logs from the following places?:
On XS IDE Log  Location: XS>Help> Open Log Directory> IDE.log file (with latest

Environment Info:
XS 5.5.4(build 15)
Comment 2 Mike Desaro 2015-01-09 09:56:28 UTC
My language and region are both US. It is really odd but XS is the only app that has this odd font bug. The steps that I follow to repro are pretty basic:

- download the latest XS
- install XS
- open XS and the fonts are as in the screen shot.

I have also added the log file that you requested to the bug report.

Just to add to this, I installed Xamarin on an iMac running 10.10 and I am seeing the exact same symbols instead of a proper font. I only have these 2 computers to test on at the moment but I'll try installed on some others when I get a chance and see if they have the same issue as well.
Comment 5 Mike Desaro 2015-01-12 15:37:44 UTC
It looks like whatever changed in 5.7 build 661 has fixed this issue on both of my computers. I didn't see anything in the release notes regarding font rendering but it is fixed. Thanks!
Comment 6 Mike Desaro 2015-11-03 14:47:48 UTC
The font rendering bug appears to be back. Testing with 5.9.8 build 0 on a retina MacBook Pro with El Capitan 10.11.1 (15B42). Same repro steps as comment 2 above. Now the interesting bit is that some dialogs such as solution options are fine but the really important bits like debugging and properties is totally busted. Latest screenshots are bused1, busted2 and works. Latest log file also included.

This may be caused by corrupted fonts in your system. Try this: open the OSX Font Book app and run the command "File > Restore Standard Fonts...". Let me know if that fixes the issue.
Comment 12 Mike Desaro 2015-11-06 12:37:53 UTC
Found the issue! It looks like Xamarin grabs the first Helvetica font installed in the system. My first Helvetica font was Fractions (a math formula font). Xamarin was using that one. I deleted the Fractions font and then Xamarin grabbed the proper Helvetica.
