We are getting extended Ascii characters in the input file and my requirement is to search and replace them with a space. I am using the following command
It is doing a good job, but in some cases it is replacing the extended characters with two spaces. So my input file is fixed length file and because of this the length is increasing by 1 character or 2 characters depending on number of extended characters in the single line.
What is the best way to replace extended characters with only one space ?
(preferably sed command)
Greetings....

In the HP Unix that i'm using when i initialise a string as Stalled="'30¬G'"
Stalled=$Stalled" '30¬C'", it is taking the character ¬ as a comma. I need to grep for 30¬G 30¬C in a file and take its count. But since this character ¬ is not being understood, the count returns a zero.

base32::hex(3tcl) Base32 encoding base32::hex(3tcl)__________________________________________________________________________________________________________________________________________________NAME
base32::hex - base32 extended hex encoding
SYNOPSIS
package require Tcl 8.4
package require base32::core ?0.1?
package require base32::hex ?0.1?
::base32::hex::encode string
::base32::hex::decode estring
_________________________________________________________________DESCRIPTION
This package provides commands for encoding and decoding of strings into and out of the extended hex base32 encoding as specified in the
RFC 3548bis draft.
API
::base32::hex::encode string
This command encodes the given string in extended hex base32 and returns the encoded string as its result. The result may be padded
with the character = to signal a partial encoding at the end of the input string.
::base32::hex::decode estring
This commands takes the estring and decodes it under the assumption that it is a valid extended hex base32 encoded string. The
result of the decoding is returned as the result of the command.
Note that while the encoder will generate only uppercase characters this decoder accepts input in lowercase as well.
The command will always throw an error whenever encountering conditions which signal some type of bogus input, namely if
[1] the input contains characters which are not valid output of a extended hex base32 encoder,
[2] the length of the input is not a multiple of eight,
[3] padding appears not at the end of input, but in the middle,
[4] the padding has not of length six, four, three, or one characters,
CODE MAP
The code map used to convert 5-bit sequences is shown below, with the numeric id of the bit sequences to the left and the character used to
encode it to the right. The important feature of the extended hex mapping is that the first 16 codes map to the digits and hex characters.
