Bug ID: 53550
           Summary: Some Catalan locales not properly handled
           Product: Wine
           Version: 7.12
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

      Distribution: ---

My system has locale ca_AD.UTF-8 which is for Catalan. However Wine apparently
does not recognize it as Catalan, it only recognizes ca_ES.

How to reproduce:

LANG=ca_AD.UTF-8 winecfg -> UI is shown in English (wrong).
LANG=ca_ES.UTF-8 winecfg -> UI is shown in Catalan (right).
LANG=ca_FR.UTF-8 winecfg -> UI is shown in English (wrong).
LANG=ca_IT.UTF-8 winecfg -> UI is shown in English (wrong).

I have actually discovered this while running YY-CHR
(https://appdb.winehq.org/objectManager.php?sClass=version&iId=22701). Running
this program with WINEDEBUG=nls I have discovered that ca_ES is mapped to
locale CAT and ca_AD and the others to ZZZ.
