...a possibly trivial, follow-up question.
Is it possible to treat several characters as a single option within a character set?
For instance, some of my routing table entries begin with "D EX" or "S*"
Is it possible to somehow include these strings along with the individual characters in the set [DCS] (and obviously match on and move these strings to the end end of their respective line before evaluating the individual characters) or would I need something like a separate invocation of SED to do this?
Thanks!

encoding
encoding(n) Tcl Built-In Commands encoding(n)
__________________________________________________________________________________________________________________________________________________
NAME
encoding - Manipulate encodings
SYNOPSIS
encoding option ?arg arg ...?
_________________________________________________________________
INTRODUCTION
Strings in Tcl are encoded using 16-bit Unicode characters. Different operating system interfaces or applications may generate strings in
other encodings such as Shift-JIS. The encoding command helps to bridge the gap between Unicode and these other formats.
DESCRIPTION
Performs one of several encoding related operations, depending on option. The legal options are:
encoding convertfrom ?encoding? data
Convert data to Unicode from the specified encoding. The characters in data are treated as binary data where the lower 8-bits of
each character is taken as a single byte. The resulting sequence of bytes is treated as a string in the specified encoding. If
encoding is not specified, the current system encoding is used.
encoding convertto ?encoding? string
Convert string from Unicode to the specified encoding. The result is a sequence of bytes that represents the converted string.
Each byte is stored in the lower 8-bits of a Unicode character. If encoding is not specified, the current system encoding is used.
encoding names
Returns a list containing the names of all of the encodings that are currently available.
encoding system ?encoding?
Set the system encoding to encoding. If encoding is omitted then the command returns the current system encoding. The system encod-
ing is used whenever Tcl passes strings to system calls.
EXAMPLE
It is common practice to write script files using a text editor that produces output in the euc-jp encoding, which represents the ASCII
characters as singe bytes and Japanese characters as two bytes. This makes it easy to embed literal strings that correspond to non-ASCII
characters by simply typing the strings in place in the script. However, because the source command always reads files using the ISO8859-1
encoding, Tcl will treat each byte in the file as a separate character that maps to the 00 page in Unicode. The resulting Tcl strings will
not contain the expected Japanese characters. Instead, they will contain a sequence of Latin-1 characters that correspond to the bytes of
the original string. The encoding command can be used to convert this string to the expected Japanese Unicode characters. For example,
set s [encoding convertfrom euc-jp "xA4xCF"]
would return the Unicode string "u306F", which is the Hiragana letter HA.
