I know that this question is not ritual because I do not offer a minimal
example, but at the moment I have not been able to identify the source
of the problem and therefore to produce a MWE.
Most of the labels of the bibliography entries in my databases are in
this form:
Author:Shorttitle
Suddenly, compiling a file with tex4ht (for LibreOffice, therefore
oolatex) produced this error: during compilation, all the labels where
altered to the form:
Author:{}Shorttitle
and therefore biber could not find them (biber version: 2.4). I tried to
edit the bcf file manually and to run again oolatex but I did not
succeed. Also deleting all the ancillary files was of no use. No problem
for label not featuring a colon (':').
If some kind soul has an idea of the possible reason of the problem
thanks, otherwise I'll try to isolate the problem and to produce a MWE.
Thank you for your kind attention,
g
