[Bug 1405684] Re: mount: codepage mapping does not work for msdos fs

 

Docs is the man page. Are there any other docs?

The MSDOS fs does not allow neither the utf8 flag nor the iocharset= option.
(this is a bug in the manpage, where iocharset=is mentioned in the FAT section)

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
