Does this means I am not innovative or dumb...I know how to script...why this stuff did not come to my mind?
There is a one way to know, can you tell me how did you first come to know about this? I've read unix books, but none talk like this at command level.
Some of these kinds of things come with time, and experience and through asking questions as you did. Hard to say when I first learned something like this. The one thing that I do know is that I tend to learn something new with nearly every question that I answer. This turns out to be no exception when looking at jlliagre's post -- I tend to think in traditional if-then-else constructs when I depend on successful command execution and thus don't think about the
command && command style one liners which as pointed out is better than simply banging two commands onto one line.

NAME
page_util_quote - page character quoting utilities
SYNOPSIS
package require page::util::quote ?0.1?
package require snit
::page::util::quote::unquote char
::page::util::quote::quote'tcl char
::page::util::quote::quote'tclstr char
::page::util::quote::quote'tclcom char
_________________________________________________________________
DESCRIPTION
This package provides a few utility commands to convert characters into various forms.
API
::page::util::quote::unquote char
A character, as stored in an abstract syntax tree by a PEG processor (See the packages grammar::peg::interpreter, grammar::me, and
their relations), i.e. in some quoted form, is converted into the equivalent Tcl character. The character is returned as the result
of the command.
::page::util::quote::quote'tcl char
This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser, will
regenerate the character in question and is 7bit ASCII. The string is returned as the result of this command.
::page::util::quote::quote'tclstr char
This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser and
will generate a human readable representation of the character in question. The string is returned as the result of this command.
The string does not use any unprintable characters. It may use backslash-quoting. High UTF characters are quoted to avoid problems
with the still prevalent ascii terminals. It is assumed that the string will be used in a double-quoted environment.
::page::util::quote::quote'tclcom char
This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser when
used within a Tcl comment. The string is returned as the result of this command.
