            Bug ID: 70742
          Assignee: portland-bugs at lists.freedesktop.org
           Summary: xdg-desktop-menu improperly check for vendor prefix on
                    Estonian locale
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: marmarek at mimuw.edu.pl
          Hardware: All
            Status: NEW
           Version: 1.1.0
         Component: xdg-utils
           Product: Portland

On Estonian locale this can happen:
xdg-desktop-menu: filename 'Uss-vm.directory' does not have a proper vendor
prefix
A vendor prefix consists of alpha characters ([a-zA-Z]) and is terminated with
a dash ("-"). An example filename is 'example-Uss--vm.directory'
Use --novendor to override or 'xdg-desktop-menu --manual' for additional info.

The reason is usage of [a-zA-Z] in check_vendor_prefix function, without
specifying explicit locale. In case of Estonian, 'z' isn't the last letter...

Simple check:
$ echo 'w' | LC_COLLATE=C grep -q '[a-zA-Z]'; echo $?
0
$ echo 'w' | LC_COLLATE=et_EE grep -q '[a-zA-Z]'; echo $?
1

It should either use explicit locale, or use '[[:alpha:]]' instead. Not sure
which is better (and more compliant with the standard).
