Bugfix by [Nutron2112](https://github.com/Nutron2112) that fixes an out of range error.
0.3.13
more robustness
0.3.12
This version can handle non-utf-8 files better.
0.3.11
Better tested latex flattening. Still not absolutely reliable: I don't have the time to write a full parser for LaTeX but primarily just have a set of regular expressions. Gets the job done for most documents. Do not use for production level stuff.
