Resulting Unicode characters not usable
Hi! Everything seems to work great so far.
The only issue I've encountered is the treatment of 2-char codes. The resulting CSS from Fontastic includes the codes like `'\u61'`.
When parsed into an Iconic library, Android Studio complains that these are invalid escape sequences.
I've fixed it manually by turning them into `'\u0061'` codes, by adding 00.

Now, the issue is that I keep adding individual icons over time and update the generated library. This process would mean I'd have to replace these codes every time.
Could this be done automatically in the script that generates the font.java class? A simple check where, if the code is 2-character, append 00. This does not change the semantics but helps with Android Studio lint and compilation.

If you could point me to the location of the parser, I might look into it.
