Additional formatting rules have been applied to the pronoun field to hopefully make it display more consistently.
Is there really a need for consistency? With these changes, non-English characters are no longer supported, which I know some people were using. And why do pronouns need to be capitalized anyway?
As far as I can tell it's just a string formatting function, and from trying a few different inputs, with these new changes the following steps (more or less) are applied for formatting:
1. Remove characters that aren't a-z, A-Z, or spaces.
2. Split string at spaces.
3. Capitalize first letter of each pronoun
4. Combine pronouns with slashes between
If you remove just punctuation/whitespace (I'm sure there are tables for this) and keep actual characters, then capitalize the first character if they can be capitalized (again, pretty sure there are lookup tables for this), I don't see why that wouldn't work outside of weird edge cases. Are there any technical limitations here?
