After you install a new font, copy it to the C:\Windows\fontsCV folder for the font to be visible and usable in the applications.
in AppVol 2.11 is a bug about fonts integration.
It doesn't work that fonts are loaded, if they are in an appstack. I talked also with vmware support.
My solution for that is to remove all fonts content from the appstack (c:\Windows\fonts and registry).
Deploy the necessary fonts with a third party tool and VMware UEM.
