The following table shows all of the valid graphemes usable as opening and closing paired delimiters in such constructs as Pod6 declarator blocks. Note they are shown between pipe symbols so the extra bounding space for any wide characters can be seen.

The data source for the table is the $brackets string defined in the HLL::Grammar module in the github.com/Raku/nqp repository.

The data are arranged in the order found in the source string. Each opening bracket is shown in its printed form followed by its paired closing bracket. Each pair is then followed by its codepoints. There are two sets of bracket pairs shown per table row.
