Thanks, though it seems to have broken some internationalisation
support. I was trying to see what would happen for month names
that include that \203 byte (like October in ar_AE.UTF-8), but
it seems to also break with some other byte values:

Without the fix:

~$ LC_ALL=ar_AE.UTF-8 date -d @0 +%b | hd
00000000  d9 8a d9 86 d8 a7 0a                              |.......|
00000007
~$ LC_ALL=ar_AE.UTF-8 strftime %b 0  | hd
00000000  d9 8a d9 86 d8 a7 0a                              |.......|
00000007

With the git head:

~$ LC_ALL=ar_AE.UTF-8 strftime %b 0  | hd
00000000  d9 d9 d8 a7 0a                                    |.....|
00000005

I suppose those 8a 86 are special as well.

For \203 0x83:

~$ LC_ALL=ar_AE.UTF-8 date -d @1443697200 +%b | hd
00000000  d8 a3 d9 83 d8 aa 0a                              |.......|
00000007
~$ LC_ALL=ar_AE.UTF-8 strftime %b 1443697200 | hd
00000000  d8 a3 d9 f8 aa 0a                                 |......|
00000006
