The problem is that input_char is external input I have no control over, I need
to sanitize it.
I tried this:
typeset -A foo=([']']="right brace")
typeset input_char="]"
typeset element=foo["$(printf "%q" "${input_char}")"]
typeset -n reference="${element}"
print "foo[']']=${reference}"
but it doesn't work either.
I could manually search and replace each occurrence of "]" with "\]", this here
works:
typeset -A foo=([']']="right brace")
typeset input_char="]"
input_char="${input_char//]/\\]}"
typeset element=foo["${input_char}"]
typeset -n reference="${element}"
print "foo[']']=${reference}"
Are there any other "special" characters which need to be taken care of?
