Unicode Support

[nzain]

PDF does not support standard encodings like UTF-8. Support for windows code pages (7bit ASCII + 1bit into Codepage) is easy to realize and probably works already (did not test). However, writing any characters beyond requires a lot of work.

For now this issue is just a pointer for later reference. I'll add more information when I find the time, including my understanding of the todos plus some example PDF files.
