I’ve never had to change the font face in Web Interface previously but I’ve had to it today for the first time ever. Now you would think that this would be in a custom style sheet file somewhere, but the CSS is actually inline in the Web Interface web pages. To change the font face you will need to edit one of the language files. In my case this was the English language file - common_strings.properties. At about line 374 you will find the following line which you modify to change the font:
FontFace=Verdana, Arial, Helvetica, sans-serif
The default location for the language file for Web Interface 4.5 is C:\Program Files\Citrix\Web Interface\4.5\languages.
