Your take: for maintainability, is it better to use
these unicodes or to just stick with escaping things?
I don't think there's a maintainability issue with Unicode
operators, because everyone has a plain ASCII counterpart; besides,
their meaning is quite apparent or in some cases even better than
their ASCII counterpart: consider the set union operator ∪ vs (|),
the first being the universally accepted mathematical symbol, while
I find the second difficult to interpret and remember.
