If you have a BibTeX entry with the author "B\"{u}hler", it is represented in
the info field of the citation dialog as "Büℎler".
I.e., the "h" character gets replaced by the PLANCK CONSTANT character, which
is defined in unicodesymbols as
0x210e "" "" "" "h" # PLANCK CONSTANT
I think the reason is that Encodings::fromLaTeXCommand, to which BiblioInfo
passes the substring "\"{u}hler", is not aware whether it is in texted or
mathed. Thus it finds the PLANCK CONSTANT for "h" and replaces that.
Ideas?
