Character escaping

[haji-ali]

Thank you again for implementing the escaping of characters and using LaTeX commands instead of unicode. I have a large bibliography which betterbib processes almost perfectly.

However, I noticed the following problems:

• For fields or entries that are not in CrossRef, betterbib escapes characters when it shouldn't. Perhaps escaping characters should not be done to fields that are already in the bib file, but for those that are obtained from external sources.

• Characters (like _) in url and doi should not be escaped (even if the entry is obtained from external sources).

@inproceedings{randompaper,
 author = {J\"oe D\'oe},
 editor = {de Groen, P. and Beauwens, R.},
 title = {An \^intesting title},
 booktitle = {{My book}},
 url={https://doi.org/10.1007/978-3-319-04537-5_3},
 doi={10.1007/978-3-319-04537-5_3},
}

which outputs

@inproceedings{randompaper,
 author = {D{\textbackslash}'oe, J{\textbackslash}''oe},
 editor = {de Groen, P. and Beauwens, R.},
 title = {An \^intesting title},
 booktitle = {\{My book\}},
 url = {https://doi.org/10.1007/978-3-319-04537-5\_3},
 doi = {10.1007/978-3-319-04537-5\_3},
}

Running betterbib again leads to more unnecessary escaping.

@inproceedings{randompaper,
 author = {D\{{\textbackslash}textbackslash\}'oe, J\{{\textbackslash}textbackslash\}''oe},
 editor = {de Groen, P. and Beauwens, R.},
 title = {An \^intesting--title},
 booktitle = {{\textbackslash}\{My book{\textbackslash}\}},
 url = {https://doi.org/10.1007/978-3-319-04537-5{\textbackslash}\_3},
 doi = {10.1007/978-3-319-04537-5{\textbackslash}\_3},
}

Unfortunately, I have no time for this anymore right now.

This is now fixed.
