When I change font on my theme I get strange characters

[patbuchanan]

When I change the font in my theme I noticed that I'm getting some strange characters where the dropdown box appears and the icons when I normally hover over objects.  Anyone know how to correct that in my theme?  I've tried a few different fonts in my theme.css file.

i've tried:

.qv-object * {
font-family: 'Roboto', 'sans-serif' !important;
}

or

.qv-object * {
font-family: 'Verdana, Geneva, sans-serif' !important;
}

and get the strange characters and figure I'm just missing something in my code:
