The GuitarPro 5 script (http://www.playonlinux.com/repository/?script=234) install wine 0.9.57, but in that vesion some fonts aren't shown.
The solution is to run GuitarPro 5 with another later version where they work. I used wine 1.1.24 and it worked great and show me all fonts.

Ok, Thanks for info. I corrected that.

I suggest you to set version to 1.1.24. For example, 1.1.25 has some problems. 1.1.24 works fine, I think. (If someone has tested any better, write it here!)

Ok, once again thanks for suggestions

Hi,

I have always used the wine version 0.9.57 without any problems with fonts. After version 0.9.57, a problem often occurs and it is reported on wineHQ : http://bugs.winehq.org/show_bug.cgi?id=17538

Guitar Pro 5 is not usable with this bug, this error is always shown and we cannot do anything.

I am on Ubuntu x64. What version on Linux are you using ?

Ok, i reverted my change so it uses Wine-0.9.57

I have with 0.9.57 the problem of the fonts again... but...
ktulu77, can you print a tab with GuitarPro?
I can't with any version of wine
