fix: special characters in enum values

[panwauu]

Description
I added a Helper Function to resolve ascii characters that are not numbers or letters ([0-9a-zA-Z]) and translate them to english. - becomes minus, + becomes plus ...
The function also accepts characters to be ignored and a seperator string to seperate the translated characters from the rest.
Applied this function to the enum renderer to resolve the issue

@panwauu you have one sonarcloud code smell :)

This looks great, good job! 🎉

Do you want to create the follow-up issue, that enum: ['test+', 'test_plus'] causes clashes, as both will generate TEST_PLUS name?
