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.

srec_ascii_hex - Ascii-Hex file format
DESCRIPTION
This format is also known as the Ascii-Space-Hex or Ascii-Hex-Space format. If you know who invented this format, please let me know. If
you have a better or more complete description, I'd like to know that, too.
The file starts with a start-of-text (STX or Control-B) character (0x02). Everything before the STX is ignored.
Each data byte is represented as 2 hexadecimal characters, followed by an "execution character". The default execution character is a
space, although many programs which write this format omit the space character immediately preceding end-of-line.
The address for data bytes is set by using a sequence of $Annnn, characters, where nnnn is the 4-character ascii representation of the
address. The comma is required. There is no need for an address record unless there are gaps. Implicitly, the file starts a address 0 if
no address is set before the first data byte.
The file ends with an end-of-text (ETX or Control-C) character (0x03). Everything following the ETX is ignored.
It is also possible to specify a running 16-bit checksum using a sequence of $Snnnn, characters, although this usually appears after the
ETX character and is thus often ignored.
Variant Forms
In addition to a space character, the execution character can also be percent (%) called "ascii-hex-percent" format, apostrophe (') or
comma (,) called "ascii-hex-comma" format. The file must use the same execution character throughout.
If the execution character is a comma, the address and checksum commands are terminated by a dot (.) rather than a comma (,).
Size Multiplier
In general, binary data will expand in sized by approximately 3.0 times when represented with this format.
EXAMPLE
Here is an example ascii-hex file. It contains the data "Hello, World[rq] to be loaded at address 0x1000.
^B $A1000,
48 65 6C 6C 6F 2C 20 57 6F 72 6C 64 0A ^C
