Unix:
To see the unusual characters in a file in octal (the less unusual characters come out as \x. e.g. Tab is "\t").
Code:
sed -n l filename
Once you know the octal representation you can get the character into an environment variable with unix echo. My echo doesn't have the "-n" switch (no newline).
e.g. For the simple case of a tab character:
Code:
TAB=`echo "\0011\c"`
We can then use ${TAB} in a sed.
The common characters are listed in unix "man ascii". In your case the character is probably a higher value than those in "man ascii" but this "man" page is a good reference for converting between number bases (octal, decimal, hexadecimal).
Now for M$ Windows:
Once you have the octal value of the character you can convert to decimal (mathematics).
Say if you need to generate the unusual character in Windows Notepad:
Ensure that numlock is on.
Press and hold ALT then type the decimal version of the character on the numeric keyboard.
For example, the Euro Sign (€) is ALT+0128 .

Hello,
When I run this UNIX code without the -t option it gives me the desired results.
The code keeps the record with the greatest datetime based on the key columns.

Hello,
With bash-script (ubunto server) I'm trying to read a binary file and, for each character, give back its ascii code (including extended ascii). For example:
