What happens to latex encoded titles? .e.g If i have some Unicode latex stuff in there

I agree. This PR helps in updating a complete BibTeX database with more than 100 entries. I could go manually through it and tell others to do the same. However, I like automating things. This option offers a functionality requested to me multiple times by different persons. I could also explain the protected terms thing, but I do not want to force people to use JabRef in a certain way if there is an easy other way.

In the default configuration, the formatter runs as last. Thus, the protection functionality comes at last. I tried it out:

title = {Än interesting Historüüü}

becomes

title = {{{{\"{A}}}n interesting Histor{\"{u}}{\"{u}}{\"{u}}}

Without the new formatter:

title = {{{\"{A}}}n interesing Histor{\"{u}}{\"{u}}{\"{u}}}

Okay good! From my point of view good

It is usually recommended to only "protect" acronyms or proper names and leave the rest to the citation style. In the bibtex world, the citation style decides the general casing of content words. Thus, I'm not sure if we should add a formatter that encourages the non-standard approach.

I do not want to train 90% of the people to do the right thing we believe in. Sometimes, I just want to get a paper finished to the deadline and not spending time educating people in BibTeX. 😇 We could add a warning in the documentation to encourage other behavior.

Other stream of argumentation: None of us found time to work on the ProtectedTermsFormatter to include more words. This PR is a work around. 😇
