My take is the $ is literal, but regex keep morphing under my feet:

Regular-Expressions.info - Regex Tutorial, Examples and Reference - Regexp Patterns

I usually just use the tab key or ctrl-V ctrl-whatever, in ' ', or $(echo a|tr 'a' '\027') (but my tr only does octal). But I use ksh, this is a bash-ism:
Code:
$ bash <<!
echo $'\x61'
!
a
$
