remove special characters
hello all
I am writing a perl code and i wish to remove the special characters for text.
I wish to remove all extended ascii characters. If the list of special characters is huge, how can i do this using substitute command
s/specialcharacters/null/g
I really want to code like
s/chr(128)..chr(256)//g... but this will not work. chr function is not working in the substitute command.
How can i do this on a single command line

SYNOPSIS
/usr/sbin/labelit -F hsfs [generic_options] [-o specific_options] special
DESCRIPTION
labelit can be used to provide labels for unmounted CD-ROM images (CD-ROMs may not be labeled, as they are read-only media).
generic_options are options supported by the generic labelit command.
If no specific_options are specified, labelit prints the current value of all label fields.
The special name should be the physical disk section (for example, /dev/dsk/c0d0s6).
OPTIONS
-o Use one or more of the following name=value pairs separated by commas (with no intervening spaces) to specify values for specific
label fields. According to the ISO 9660 specification, only certain sets of characters may be used to fill in these labels. Thus,
``d-characters'' below refers to the characters `A' through `Z', the digits `0' through `9', and the `_' (underscore) character.
``a-characters'' below refers to `A' through `Z', `0' through `9', space, and the following characters: !"%&'()*+,-./:;<=>?_.
