[Bug 1405684] Re: mount: codepage mapping does not work for msdos fs
utf8 and iocharset do not make sense when LFNs are not allowed. codepage
is the only info required to interpret short filenames.

Title:
mount: codepage mapping does not work for msdos fs
Status in util-linux package in Ubuntu:
New
Bug description:
I want to mount a DOS 5.0 partition without messing it up with LFNs.
According to docs this only works if I use the MSDOS fs instead of
VFAT.
But using MSDOS fails converting non ASCII chars.
If I mount this way:
mount -t vfat -o check=strict,codepage=850,iocharset=iso8859-1,utf8
everything is fine:
ÄÄÄÄÄÄÄÄÄÄ AßLAR ÄÜÖßÄÜÖ istdaskürzer nochlänger
ABC ÄÜÖÄÜÖ äüößÄÜÖ2 longfilename öööööööööö
If I mount using MSDOS
mount -t msdos -o check=strict,codepage=850
the chars aren't translated at all:
ls shows garbage:
?????? ????? ??????~1 ??????~1 ?????2 abc a?lar istdas~1 longfi~1 nochl?~1
if piped through less, you can see it delivers the cp850 codes.
<8E><9A><99><8E><9A><99>
<8E><9A><99><U+139A><99>
<99><99><99><99><99><99>~1
<8E><8E><8E><8E><8E><8E>~1
<8E><9A><99><U+139A><99>2
abc
a<E1>lar
istdas~1
longfi~1
nochl<8E>~1
Writing filenames directly writes UTF8 codes on the disk (I believe,
not verified)
thanks
