The query should check for characters which is not present in the following
A to Z,
a to z ,
0 to 9
You have already solved the problem almost - all on your own. Just construct a simple regular expression from your goal:
will find any characters which are not small characters, capitalized characters, digits or some punctuation characters. Add in the brackets more punctuation characters to exclude them too from the found characters as per your request. Now put this mechanism to work with "sed" or whatever:
will delete all the characters not covered in the regexp and write the result to a file. Check this file and modify the regexp as necessary depending on the result.

__________________________________________________________________________________________________________________________________________________NAME
textutil::split - Procedures to split texts
SYNOPSIS
package require Tcl 8.2
package require textutil::split ?0.7?
::textutil::split::splitn string ?len?
::textutil::split::splitx string ?regexp?
_________________________________________________________________DESCRIPTION
The package textutil::split provides commands that split strings by size and arbitrary regular expressions.
The complete set of procedures is described below.
::textutil::split::splitn string ?len?
This command splits the given string into chunks of len characters and returns a list containing these chunks. The argument len
defaults to 1 if none is specified. A negative length is not allowed and will cause the command to throw an error. Providing an
empty string as input is allowed, the command will then return an empty list. If the length of the string is not an entire multiple
of the chunk length, then the last chunk in the generated list will be shorter than len.
::textutil::split::splitx string ?regexp?
This command splits the string and return a list. The string is split according to the regular expression regexp instead of a simple
list of chars. Note that if you parentheses are added into the regexp, the parentheses part of separator will be added into the
result list as additional element. If the string is empty the result is the empty list, like for split. If regexp is empty the
string is split at every character, like split does. The regular expression regexp defaults to "[\t \r\n]+".
