That's correct. In shell glob pattern bracket expressions, the standard
negator is '!' and not '^'. Many shells support '^' as a synonym, but
that's an extension to the standard and not mandatory. Dash usually
doesn't support such extensions. But all shells support '!', so just
that instead and you're safe.

"If an open bracket introduces a bracket expression as in XBD RE Bracket
Expression, except that the <exclamation-mark> character ( '!' ) shall
replace the <circumflex> character ( '^' ) in its role in a non-matching
list in the regular expression notation, it shall introduce a pattern
bracket expression."
