Latex2Unicode Formatter: Captial letters after an underscore are wrapped in braces

[Siedlerchr]

While checking the problem with the Underscores in the groups from #2599, I noticed it's a problem of the Latex2Unicode formatter:

Create a new entry with title Underscore_Underscore
Save
In the main table the entry is shown as Underscore_(U)nderscore

Is it possible to file an issue at https://github.com/tomtung/latex2unicode/issues?

Hmm I think the behavior of determining subscript is consistent with latex (although if not in the math environment a compile error would be thrown). In other words, I guess latex2unicode is doing its job as intended?

Maybe JabRef can add some extra logic to determine when latex2unicode should kick in?

When interpreting _ with LaTeX, the _ command is a command stating that the following character should be go to subscript. If one does not want that, one has to load the underscore package. See http://tex.stackexchange.com/q/48632/9075.

Maybe, JabRef should escape the underscore when doing the conversion (this assumes that the user loads the underscore package)? Or warn the user?

Solution idea: _ is only converted if followed by _{...} . - IDEA: replace _ by ARBITRARYSTRING, then convert to unicode and then convert back.

@tomtung probably, in text_u the u should be converted to subscript letter in unicode and show it as textᵤ

[tomtung]

@tobiasdiez yeah that's the current behavior. Also I use _(whatever) to represent subscript when there are no corresponding Unicode subscript characters available.
