Control B in standard ASCII (STX) is decimal 02 or ^B according to the list of ASCII values. Not a smiley face.
Windows has different keyboard setups from UNIX. In UNIX they are called locales. What you see is standard, the Windows smiley or whatever is Windows only, for what you are doing.
I am assuming you are telnet to another unix box. If not, what you see when you type on a UNIX machine can be different in a DOS window. Telnet also responds to some keystrokes as well instead of just printing them. Be careful. Read your man page for telnet to see what keystrokes (or combinations) have meaning.
One way to get around this:
To get colors and other effects requires that the both terminals in the conversation use ANSI escape sequences:

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.

ASCII(1) General Commands Manual ASCII(1)
NAME
ascii, unicode - interpret ASCII, Unicode characters
SYNOPSIS
ascii [ -8 ] [ -oxdbn ] [ -nct ] [ text ]
unicode [ -nt ] hexmin-hexmax
unicode [ -t ] hex [ ... ]
unicode [ -n ] characters
look hex /lib/unicode
DESCRIPTION
Ascii prints the ASCII values corresponding to characters and vice versa; under the -8 option, the ISO Latin-1 extensions (codes 0200-0377)
are included. The values are interpreted in a settable numeric base; -o specifies octal, -d decimal, -x hexadecimal (the default), and -bn
base n.
With no arguments, ascii prints a table of the character set in the specified base. Characters of text are converted to their ASCII val-
ues, one per line. If, however, the first text argument is a valid number in the specified base, conversion goes the opposite way. Control
characters are printed as two- or three-character mnemonics. Other options are:
-n Force numeric output.
-c Force character output.
-t Convert from numbers to running text; do not interpret control characters or insert newlines.
Unicode is similar; it converts between UTF and character values from the Unicode Standard (see utf(6)). If given a range of hexadecimal
numbers, unicode prints a table of the specified Unicode characters -- their values and UTF representations. Otherwise it translates from
UTF to numeric value or vice versa, depending on the appearance of the supplied text; the -n option forces numeric output to avoid ambigu-
ity with numeric characters. If converting to UTF , the characters are printed one per line unless the -t flag is set, in which case the
output is a single string containing only the specified characters. Unlike ascii, unicode treats no characters specially.
The output of ascii and unicode may be unhelpful if the characters printed are not available in the current font.
The file /lib/unicode contains a table of characters and descriptions, sorted in hexadecimal order, suitable for look(1) on the lower case
hex values of characters.
EXAMPLES
ascii -d
Print the ASCII table base 10.
unicode p
Print the hex value of `p'.
unicode 2200-22f1
Print a table of miscellaneous mathematical symbols.
look 039 /lib/unicode
See the start of the Greek alphabet's encoding in the Unicode Standard.
