You need to check your reading comprehension. After his second post clarified, that was clearly the goal.

What
else is a computer going to use, when reading bytes from a file? We're talking about programs and pipes -- not a unicode-aware text viewer. He'd have to go to special, extreme effort to
not read in sizes of bytes.

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.
