Hi.

You could try:

Code:
bold=`tput smso`
offbold=`tput rmso`

or
bold=`tput bold`
offbold=`tput sgr0`

Then echo $[bold} to switch it on, and echo ${offbold} to switch it off.

Code:
bold=`tput bold`
offbold=`tput sgr0`

echo "This word is ${bold}bold${offbold} and this is not"


This word is bold and this is not

How it works depends on your terminal capabilities.

Code:
man tput

There are two different versions of tput; one uses the terminfo database, the other the termcap database.

As I wrote in Pro Bash Programming (publication date is next Monday, Oct. 19):

Unix purists will shake their heads over this chapter. Traditionally, screen manipulation is done through the termcap or terminfo database that supplies the information necessary to manipulate any of dozens or even hundreds of types of terminal. The shell interface to the database is an external command, tput.

On some systems, tput uses the termcap database; on others (mostly newer systems) it uses the terminfo database. The commands for the two databases are not the same, so a tput command written for one system may not work on another.

On one system, the command to place the cursor at the 20th column on the 10th row is:

tput cup 9 19

On another system, the command is:

tput cm 19 9

These commands will produce the correct output for whatever type of terminal is specified in the TERM variable. (Note: tput starts counting at 0.)

However, the plethora of terminal types has, for all intents and purposes, been reduced to a single, standard type. This standard, ISO 6429 (also known as ECMA-48, and formerly known as ANSI X3.64 or VT100), is ubiquitous, and terminals that do not support it are few and far between. As a result, it is now feasible to code for a single terminal type. One advantage of this homogeneity is that the necessary coding can be done entirely within the shell. There's no need for an external command.
This is the code to use:

Code:
printf "\e[1m"  ## bold on
printf "\e[0m"  ## bold (and other attributes) off

As I already replied in a different thread you wrongly open, there is no standard way to achieve what you want. That will mainly depends on how you view the file. ksh or any other shell is irrelevant.

What happens if you use tput smso and tput rmso?

fpmurphy, I'm afraid you are missing the issue is not that much the encoding but how the file is viewed.
"cat", "less -r" should work assuming the terminal emulator is complying but "less", "vi" and other editing commands will lead to what the OP experiments.
