These are stable names, so we shouldn't change the spelling lightly.

Also, the "specializations" part in the stable name could benefit from some abbreviation, for the benefit of indexes etc.

I'm not sure if there's a) any way to "resolve" this issue, and b) any problem that needs to be solved here.

Well, I guess the obvious way to resolve this is to change "wchar.t" to "wchar_t". But if the theory is that such a punctuation fix would tremendously inconvenience people when they read the existing stable name somewhere and try to look it up, then by all means close this ticket (because while I find that thoroughly unconvincing, I'm not interested in arguing that point).

I'm still unconvinced that there is a problem here that needs to be solved. Stable names are called stable because we don't generally change them, so I'd like to see a much more convincing analysis spelled out why you think this is needed. Feel free to reopen if you have one.
