Hi ignatius...
If I am reading your post correctly it seems you are expecting the built-in CP 437, default IBM CGA graphics card characters to work.
MS-DOS, IBM-DOS and others could access these and also DOS extended characters too but UNIX/Linux/Minix/OSX etc... are not the same animals.
The characters were also available on much, much later graphics cards but AFAIK they are not readily available via an 8 bit code page any more.
The industry has evolved from Code Pages to UNICODE so you will have to search for the characters under these conditions, IF, that is what you are after.
As Jim says the control characters do other things inside the *NIX environment.
To check the smiley face you see in Linux do this:
_Copy_the_graphic_ and do the next:
hexdump -C <<< _paste_the_graphic_ and enter it.
And post the results to let us see it.
Hope this helps.

Hi All,
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.

tr(1B) SunOS/BSD Compatibility Package Commands tr(1B)
NAME
tr - translate characters
SYNOPSIS
/usr/ucb/tr [-cds] [ string1 [string2]]
DESCRIPTION
The tr utility copies the standard input to the standard output with substitution or deletion of selected characters. The arguments string1
and string2 are considered sets of characters. Any input character found in string1 is mapped into the character in the corresponding posi-
tion within string2. When string2 is short, it is padded to the length of string1 by duplicating its last character.
In either string the notation:
a-b
denotes a range of characters from a to b in increasing ASCII order. The character , followed by 1, 2 or 3 octal digits stands for the
character whose ASCII code is given by those digits. As with the shell, the escape character , followed by any other character, escapes
any special meaning for that character.
OPTIONS
Any combination of the options -c, -d, or -s may be used:
-c Complement the set of characters in string1 with respect to the universe of characters whose ASCII codes are 01 through 0377
octal.
-d Delete all input characters in string1.
-s Squeeze all strings of repeated output characters that are in string2 to single characters.
EXAMPLES
Example 1: Creating a list of all the words in a filename
The following example creates a list of all the words in filename1, one per line, in filename2, where a word is taken to be a maximal
string of alphabetics. The second string is quoted to protect `' from the shell. 012 is the ASCII code for NEWLINE.
