Sounds like a dash bug, if my reading of 2.6.2 Parameter
Expansion is correct:

Interestingly, this works in dash:

$ foo=bar}
$ echo ${foo%'}'}
bar

but doing it inside an interpolated string doesn't:

$ foo=bar}
$ echo "${foo%'}'}"
bar}'}

This would be another way to work it around.  Both dash and bash
say 'foo':

        $ suf='^{}'
        $ name='foo^{}'
        $ echo "${name%$suf}"
        foo

I think this might be easier to read than using "^{\}".

That seems reasonable to me.
