I use Bootstrap 3.0.3 glyphicons. All is ok on desktop browsers and on Android devices. My problem is about Apple devices (tested on iPhone and iPad running iOS7).
The glyphicons look like emoticons. I've found some issues but not answering my problem.

Thank you for your help.
I encountered same issue and resolved it by removing woff2 font file from @font-face. It seems iOS doesn't support woff2.
[Updated 2016-03-02] Fix above turns out just matter of luck (timing?). @rofflox 's answer which seems to be more promising and it works for me.
