Hello,
I prefer to send my bug report here instead of registering on Bugzilla and
hope that's alright. I'm also not subscribed; please keep me CC'd.
I'm using glibc 2.30 on Debian GNU/Linux. 2.30 and 2.32 appear to have added
support for Unicode 12.1.0 and 13.0 respectively [1] [2], but stdc-
predef.h [3] even in git seems to lag behind reflecting these changes:
> /* wchar_t uses Unicode 10.0.0. Version 10.0 of the Unicode Standard is

> - 285 hentaigana
> - 3 additional Zanabazar Square characters */
> #define __STDC_ISO_10646__ 201706L
so in this way clients won't be able to know that it's supported. Except for
some possible discrepancy in Unicode Inc. and ISO/IEC's release dates,
suitable constants for 2.32 and 2.30 ought to be 202003L and 201905L
respectively [4].
Regards,
John

Mike,
Did we miss this when we update to 12 and 13?

It seems to've not been fixed in git yet, so this is a just a reminder.
