Character support in text2png

[graeham]

I've found the Matplotlib libraries seem to only support ascii. Non-supported characters result in a rectangular box on the output.

Also, new lines passed from an html form (Firefox on Linux) result in '\r\n' in the string passed stl_tools, where the \r isn't recognized as a character, and a rectangular box results in the output png.

Consider blocking non-supported characters (I adapted my local code to ignore them) or use a library which supports more characters?

Thanks for the very useful package!

Hmm, good catch. Definitely a matplotlib limitation.

some_string.encode('ascii', 'ignore')

might do the trick, but haven't tested that. I'll have to experiment.
Thanks for the feedback!

I believe I ended up implementing a similar function up-stream when my
python code read input from the html form.

Not a major issue, just thought I'd point it out in case you wanted to fix
it and also to help anyone else who runs into this!
