Hey, @fabclmnt! Don't wanna be intrusive, but could you please take a look at my PR? :)
The tests seem to fail for some external reasons not connected to changes at the code.
Thanks in advance!

sry for the delay @desobolevsky, I will be having a look at this week. My questions with this PR is more related to the root cause of the problem, which is still not clear. This workaround may lead to silent errors, since the user is expecting their unicode categories to be categorized as Other Symbol, just like 😀 and 🔥.

Also, when creating a fix for specific use case like this we expect the addition of a unit test tests/issues/test_issue1325.py to ensure the issue is fixed and we don't run into it again in the future.
