Randomly appearing control characters in text files

Hi,

From some time, we have noticed that our ascii files have started corrupting due to the presence of some random control characters (^@, ^M, ^H, ^D). The characters appear randomly on any file after the process that creates the file finishes. If we rerun the process, the files re creates perfectly without problems.

The appear on any file randomly. Their location in the file is also random. We tried a reboot of the server (AIX 5. something), but the problem still persists. We found some bad blocks on disk during reboot and then we did a restore from backup.

The problem still persists.

Thanks
Aakash

UNTEX(1)						      General Commands Manual							  UNTEX(1)

NAME
untex - strip LaTeX comands from input SYNOPSIS
untex [ options ] [ files ... ] DESCRIPTION
Untex removes some LaTeX commands from the files listed in the arguments (or standard input) and prints the output to standard output. OPTIONS
- read from standard input. -o remove options to LaTeX commands, i. e. everything in brackets [] behind a command. -i process "include{file}" and "input{file}" and "input file" commands. -m (try to) remove all math code. -u replace all "a (etc.) with ibm (CP850) characters. -uiso replace all "a (etc.) with ISO characters. -uascii replace all "a (etc.) with ascii characters. -g replace all "a (etc., from german.sty) with ibm (CP850) characters. -giso replace all "a (etc., from german.sty) with ISO characters. -gascii replace all "a (etc., from german.sty) with ascii characters. -e remove environment names. -a remove arguments of commands (not recommended). -g implies -u, -a implies -o. SEE ALSO
latex, tex, detex BUGS
The -g and -u options only work for german accented characters. Not fixed due to lack of time, any help is appreciated. The includeonly command is ignored. Using -u option in a UTF-8 terminal doesn't work. Using it alone in a Latin1 terminal doesn't work either, you must also add -uiso. AUTHORS
Untex was written by Michael Staats (michael@hal6000.thp.Uni-Duisburg.DE). The -gascii and -uascii options were added by Denis Endisch (denis@smoky.ikf.physik.uni-frankfurt.de). Thanks to Subhasish Mazumdar (mazumdar@ringer.cs.utsa.edu) for some hints for improvements and bug reports. 4th Berkeley Distribution Version 1.2 1994 April 6 UNTEX(1)
