>Description:
/usr/scr/sbin/mount_msdosfs/iso72dos, submitted by me with the PR
misc/32119 contains a few inaccuracies: ISO-8859-7 middle dot is
mapped incorrectly to CP-737 bullet operator and ISO-8859-7 capital
iota with diaeresis and capital upsilon with diaeresis are not mapped
at all to CP-737.
>How-To-Repeat:
I didn't verify the bug by experimenting with filenames in MS Windows
partitions, just trusted the CP-737 to Unicode map found in Andreas
Brouwer kbd package for Linux. Previously I used the maps found in
RFC 1947 ("Greek Character Encoding for Electronic Mail Messages") by
Diomedes Spinellis, which didn't provide a mapping to CP-737 for
capital iota and upsilon with diaeresis.
>Fix:
The necessary patch to /usr/scr/sbin/mount_msdosfs/iso72dos follows:
