G'day jwkrahn,

The following is just a point of clarification; it's not intended as a correction.

"Which are the same in Perl except for \v which Perl doesn't use."

Actually, Perl does use \v; you can't use it to insert a VT, but you can use it to detect one. See "perlrebackslash: All the sequences and escapes":

...
\v                Match any vertical whitespace character.

This was introduced in Perl v5.10: "perl5100delta: Vertical and horizontal whitespace, and linebreak".

I don't know for certain, but I imagine this is unavailable in the "TinyPerl 5.8" being used by the OP.

$ perl -we 'print "abc\vdef\n"'
Unrecognized escape \v passed through at -e line 1.
abcvdef

$ perl -we 'print "abc\x{0b}def\n"'
abc
   def
