Depending on the Operating System these might work.

Code:
grep -F -f my.mrk my.map

fgrep -f my.mrk my.map

Failing that I would carefully check that both files are unix text file format and not MSDOS. Also look for blank lines in file my.mrk which will cause a match with every line in my.map.

These sed's don't change anything but make line terminators visible. A unix format text file should just show lines terminated with a dollar sign.

Code:
sed -n l my.mrk
sed -n l my.map

make_unicodemap

MAKE_UNICODEMAP(1)														MAKE_UNICODEMAP(1)

NAME

       make_unicodemap - construct a unicode map file for Samba

SYNOPSIS

       make_unicodemap codepage inputfile outputfile

DESCRIPTION

       This tool is part of the Samba suite.

       make_unicodemap compiles text unicode map files into binary unicode map files for use with the internationalization features of Samba 2.2.

OPTIONS

       codepage
	      This is the codepage or UNIX character set we are processing (a number, e.g. 850).

       inputfile
	      This is the input file to process. This is a text unicode map file such as the ones found in the Samba source/codepages directory.

       outputfile
	      This is the binary output file to produce.

SAMBA UNICODE MAP FILES

       A  text Samba unicode map file is a description that tells Samba how to map characters from a specified DOS code page or UNIX character set
       to 16 bit unicode.

       A binary Samba unicode map file is a binary representation of the same information, including a value that specifies what codepage or  UNIX
       character set this file is describing.

FILES

       CP<codepage>.TXT

       These are the input (text) unicode map files provided in the Samba source/codepages directory.

       A text unicode map file consists of multiple lines containing two fields. These fields are :

       o character - which is the (hex) character mapped on this line.

       o unicode - which is the (hex) 16 bit unicode character that the character will map to.

       unicode_map.<codepage>  -  These are the output (binary) unicode map files produced and placed in the Samba destination lib/codepage direc-
       tory.

INSTALLATION

       The location of the server and its support files is a matter for individual system administrators. The following are thus suggestions only.

       It is recommended that the make_unicodemap program be installed under the $prefix/samba hierarchy, in a directory readable by  all,  write-
       able only by root. The program itself should be executable by all. The program should NOT be setuid or setgid!

VERSION

       This man page is correct for version 2.2 of the Samba suite.

AUTHOR

       The  original  Samba  software  and  related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.

       The original Samba man pages were written by Karl Auer.	The man page sources were converted to YODL format  (another  excellent  piece	of
       Open  Source  software,	available  at ftp://ftp.icce.rug.nl/pub/unix/ <URL:ftp://ftp.icce.rug.nl/pub/unix/>) and updated for the Samba 2.0
       release by Jeremy Allison. The conversion to DocBook for Samba 2.2 was done by Gerald Carter
