Unicode Regex Question

[Cameron Dutro]

Hey cldr-users,

I'm looking at this entry
<http://unicode.org/cldr/trac/browser/trunk/common/transforms/Any-Publishing.xml#L21>
in CLDR transforms. I'm curious why that "$" character is inside the
character class. Here's the line reproduced:

<tRule>$makeRight = [[:Z:][:Ps:][:Pi:]$] ;</tRule>

I see an outer character class that contains three internal unicode
character sets and a literal dollar sign. Usually in regular expressions,
the dollar sign is used to match the end of the string. When it's included
in a character class however, it should be interpreted as a literal
character.

Was including the dollar sign in the character class intentional? Should it
be treated as an end-of-string anchor or a literal string?
