Remove OrdinalsToSuperscriptFormatter from recommended biblatex save actions

[lenhard]

Fixes #2596

The LatexToUnicode is conflicting with the OrdinalsToSuperscriptFormatter but both are recommended for the same fields for biblatex. This PR removes the latter. Since biblatex is usually used together with UTF-8 and Unicode conversion should be sufficient.

I see that this is an issue. The initial idea is as follows:

1. No BibEntry should contain LaTeX encoded umlauts
2. Each BibEntry should use superscripts whereever possible.

Why is this not possible any more? Why can't I have properly formatted BibEntries with JabRef any more?

[Siedlerchr]

That's really weird. I never had problems with that setting

[koppor]

Yeah, I worked with that for ages. 🌞

[Siedlerchr]

Is this maybe due to the new lib?

[lenhard]

Yes, I would expect that this is due to the new lib. I assume that it leads to the following:

1. Ordinals formatter converts 2nd to 2\textsuperscript{nd}
2. Latex formatter converts 2\textsuperscript{nd} to 2ⁿᵈ
3. Ordinals formatter interprets 2ⁿᵈ as 2nd and converts it to 2\textsuperscript{nd}
4. And so on

I might be wrong though, I did not debug this.

@Siedlerchr @koppor: Do you have problems with it now? What would you recommend instead?

[koppor]

When using the defaults in the "Cleanup entries" dialog, everything works fine.

Maybe, it is possible to have different defaults for save actions and for cleanup? I really need that functionality.

[lenhard]

@koppor The problem are the defaults for biblatex, not for BibTeX, which are depicted in your screenshot above.

An alternative solution, and maybe even a better one, might be to have the ordinals formatter correctly recognize 2ⁿᵈ as ordinals, so that it does not try to replace that. Should be doable, but right now I cannot make any promises time-wise. So, if anybody wants to take this over, be my guest.

[koppor]

I am not sure whether all unicode fonts support 2ⁿᵈ. Therefore, I really like the idea to have the ordinals formatter recognize that.

[tobiasdiez]

Is it really that important to have "ordinals-to-superscript" as default to invest more energy into it? I think @lenhard's solution is fine.

You can choose between

• Everything in unicode, then you would want 2ⁿᵈ similar to ℚΔ∘ΞΛΩ -> Latex to Unicode
• Everything in latex, then it would be 2\textsuperscript{nd} or even better \nth{2} using the nth package but also \alpha, \beta, \in ... -> Unicode to Latex + Ordinals to Latex

I second Jörgs and Tobias' opinion...

[koppor]

I really like the ordinals-to-suprscript formatter as it provides great formatted bibliographies.

People write "2nd conference on something", which should appear as "2ⁿᵈ conference on something" in the proceedings. If I understand the fix correctly, biblatex papers won't have the superscript (more or less) automatically from now on.

Since most publishers use bibtex, the solution for me is to have an unclean personal biblatex file and always to the bibtex conversion when working on a paper. The superscript will be injected when copying the entry to the paper by a cleanup..
