Error with identifiers that contain special characters

[wbio99]

Good afternoon
When I try to save a project in cnapy and when I resume it, that is, reopen it, it closes immediately.
Attached error that I get in the terminal. I appreciate if you can help me.

In SBML there are several restrictions on the type of characters that an identifier can contain. A lot of commonly used names in biology violate these restrictions, so in order to make them usable as identifiers cobrapy encodes such names when saving a model as SBML and decodes them when loading. Apparently this does not always work perfectly so that an identifier beginning e.g. with "_2-" causes trouble. As a workaround you should avoid underscores at the beginning of identifiers.
