Font Awesome Issue

Question

I am trying to use fontawesome in my project but there is a problem with plane icons! they are shown as a square! for example : for using "telegram-plane" from cheatsheet I add the below code to my strings:

<string name="fa_telegram_plane">&#xf3fe;</string>

Answer 1

Use this:

<string name="fa_telegram_plane">\uf3fe</string>

Instead of this:

<string name="fa_telegram_plane">&#xf3fe;</string>

EDIT:

May be that that icon is only in the PRO release, and therefore unavailable in the FREE version.

But this one is quite similar, isn't it? \uf1d8
