Issue with tr, removing [:alnum:]

Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

Code:

1. The problem statement, all variables and given/known data:
 You 	should also know how to find files based on their characteristics.
Use 		stat to list the meta data for the file with inode number 2793324. 		Your command should suppress error messages. Hint: command 		substitution will make this easier!
 	alindner@cs215:~$ 	find / -inum 2793324 -exec stat {} \; 2> /dev/null
 	 	 File: `/usr/lib/locale/bn_IN/LC_NAME'
 	 	 Size: 130             Blocks: 8          IO Block: 	4096   regular file
 	Device: 	801h/2049d      Inode: 2793324     Links: 1
 	Access: 	(0644/-rw-r--r--)  Uid: (    0/    root)   Gid: (    0/    root)
 	Access: 	2011-04-02 19:37:31.000000000 -0400
 	Modify: 	2010-10-28 17:51:33.000000000 -0400
 	Change: 	2011-01-16 18:08:54.000000000 -0500
 	How 		many bytes would be in this file if all the 		alphas (a-z and A-Z) and all the numerics (0-9) where 		removed from it?
 
 2. Relevant commands, code, scripts, algorithms:
See 1 & 2

3. The attempts at a solution (include all code and scripts):
So i am trying to remove the Alpha and Numeric characters, so i am using tr to do this, but it keep dumping characters on my screen? when i try to do this.  Is this because when i less it it tells me its a binary file?

tr -d "[:alnum:]" < LC_NAME4

Also wasnt sure if it was an issue with permissions as well so i made copies of the file to work on and changed permissions (chmod 7777 LC_NAME4)

less LC_NAME4


^]^Q^C ^G^@^@^@$^@^@^@/^@^@^@0^@^@^@=^@^@^@S^@^@^@f^@^@^@|^@^@^@%p%t%f%t%g^@^@শ�<8D>র�<80>^@শ�<8D>র�<80>মত�<80>^@�<95>�<81>মার�<80>^@শ�<8D>র�<80>মত�<80>^@UTF-8^@
LC_NAME4 lines 1-1/1 (END)

Is there something im doing worn with tr?

4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):
KeeneState, KSC, Keene, NH, USA, Charlie W., CS215-01

Note:  Without school/professor/course information, you will be banned if you post here! You must complete the entire template (not just parts of it).

debconf-mergetemplate

DEBCONF-MERGETEMPLATE(1)					      Debconf						  DEBCONF-MERGETEMPLATE(1)

NAME

       debconf-mergetemplate - merge together multiple debconf template files

SYNOPSIS

	debconf-mergetemplate [options] [templates.ll ...] templates

DESCRIPTION

       Note: This utility is deprecated. You should switch to using po-debconf's po2debconf program.

       This program is useful if you have multiple debconf templates files which you want to merge together into one big file. All the specified
       files will be read in, merged, and output to standard output.

       This can be especially useful if you are dealing with translated template files. In this case, you might have your main template file, plus
       several other files provided by the translators. These files will have translated fields in them, and maybe the translators left in the
       english versions of the fields they translated, for their reference.

       So, you want to merge together all the translated templates files with your main templates file. Any fields that are unique to the
       translated files need to be added in to the correct templates, but any fields they have in common should be superseded by the fields in the
       main file (which might be more up-to-date).

       This program handles that case properly, just list each of the translated templates files, and then your main templates file last.

OPTIONS

       --outdated
	   Merge in even outdated translations. The default is to drop them with a warning message.

       --drop-old-templates
	   If a translation has an entire template that is not in the master file (and thus is probably an old template), drop that entire
	   template.
