Of course not.

If you look at a bib(la)tex entry it begins with '@<document_type>{'

That's followed by the label; that line ends with a comma. The closing curly
brace for the entire entry is at the end. In the meantime, the label field
has no closing curly brace so apostrophes, accents, etc. are not explicitly
displayed. Curly braces around the label field itself solve the problem
