Comment (by technosailor):

 The problem is query_var collision. sanitize_title() is going to strip
 special chars like # in C# for the slug. So C# does in fact become 'c' as
 does C++ or just C.

 I don't agree that wp_insert_term should be where the checks are
 happening. It adds a potentially unneeded query. We should not be doing
 wp_insert_term if term_exists. I believe the existing functionality is as
 it should be. I respect the problem but it's really edge and a core
 behavior modification just doesn't feel warranted. That's my opinion
 though.
