Forums Bug Reports $asc() returns empty for curly braces { }

It happens with numerous string identifiers, and not for just this version.

//echo -a $asc(}) ,
//echo -a $asc({) .
result: 44 46

//echo -a $str({,5)
//echo -a $left(},5)
result: 5
//echo -a $str({,5) anything
//echo -a $left(},5) anything
result: $null

//echo -a $sha1({) abc
//echo -a $sha256(}) abc
result: same as $sha1(abc) or $sha256(abc)
//echo -a $len({) abc
result: 3

workaround is:
//echo -a $asc( $({) ) or $asc( $eval({) )
or
//var %a { | echo -a $asc({}
or the one that assumes you already know the answer
//echo -a $asc($chr(123))

You should not expect this next to be 'fixed', as brackets outside parenthesis shouldn't be used, and from the above it doesn't like them inside anything besides $() $eval():
//var %a = } | echo -a %a
//var %a = { | echo -a %a
