I definitely need to make a new parser (instead of borrowing one from someone ><). As mentioned in ali-ramadhan/DocumenterCitations.jl#21, I will do it next month.

I plan to follow the model of Tokenize.jl, and integrate LaTeX special character and diacritical marks.

Spurious spaces troubles should be solved now (v0.2.7)
However, converting common TeX to Unicode is not possible yet. Hopefully, we can make something for the next version.

Closing this.
