Error in Cyrillic macros

[crazytexer]

When I use doi2bib.org and request a BIB data from the DOI corresponding to a paper in Russian, the Cyrillic letters are represented as \cyrchar\CYRA (for Cyrillic А), \cyrchar\CYRB (for Cyrillic Б), etc. That's fine. But very often I see an error like \cyrchar\{CYRA}. It is not a valid (La)TeX code; symbols \ and { between \cyrchar and CYRA} should be at least swapped. This is an example. In there, I see many such errors, e.g.
title = {{\cyrchar\{CYRA}}{\cyrchar\{CYRN}}{\cyrchar\{CYRA}}{%...
If you could fix that, it would be great.

OK, I see now that this bug is actually not in doi2bib so I'm closing the issue.
