Just as an idea, maybe you can check if you could include that feature request here?
#457

@Siedlerchr I've made a first attempt at adding the feature ^_^

I have a problem with testing the regexFormatter, it doesn't take protected parts of a sentence into account.

I don't really know how I can write the code so that it does take the protected characters into account, since it currently only seems to be done on a letter by letter basis.

Any ideas on how this could be done, or shall I just remove the feature here for now?

Maybe anyone of the other @JabRef/developers has an idea on how to check that

@tobiasdiez Maybe you have an idea?

Sorry, I've no deep knowledge about regular expressions in particular and about the formatters in general.

I understand the question #2663 (comment) as follows:

If I replace regex a by X and I apply it at abc{abc}, the result is Xbc{Xbc}, but it should be Xbc{abc}.

As one cannot change the regex engine, I would {...} replace by something not matched by the regular expression, then apply the regex and then change it back.

1. Replace protected terms
   1a. Replace first {...}by unicode character 2580
   1b. Replace second {...}by unicode character 2581
   1.c etc.
2. Apply regex
3. replace back

@shitikanth took over at #3096, because it is unlikely, that we get access to https://github.com/delftswa2017/jabref
