Label - replace # with Hash & other chars

[shashisadasivan]

Creating labels removes special characters from the label id.
e.g. % is replaced by P, Labels starting with numbers or special chars are removed
$,#,@ etc
We should be replacing these special chars with Words instead if possible
Current suggestion will replace the following

Special Char	Replace with
#	Hash
@	At
!	Ex
$	Dollar
^	Exp
&	Amp
*	Star
+	Plus
-	Dash
|	Pipe
\	BSlash
/	FSlash
=	Equal
_	Underscore
~	Tilde
%	P
