One eval-free, 100% pure Bash possibility:

#!/bin/bash

die() {
   printf >&2 "%s\n" "$@"
   exit 1
}

aryname=''
linenb=0
while read line; do
   ((++linenb))
   if [[ $line =~ ^[[:space:]]*$ ]]; then
      continue
   elif [[ $line =~ ^\[([[:alpha:]][[:alnum:]]*)\]$ ]]; then
      aryname=${BASH_REMATCH[1]}
      declare -A $aryname
   elif [[ $line =~ ^([^=]+)=(.*)$ ]]; then
      [[ -n aryname ]] || die "*** Error line $linenb: no array name defined"
      printf -v ${aryname}["${BASH_REMATCH[1]}"] "%s" "${BASH_REMATCH[2]}"
   else
      die "*** Error line $linenb: $line"
   fi
done

Reads on standard input. If you want to read from a file, change the done by:

done < "filename"

Lines of the form

space and funnŷ sÿmbòl=value that will have an equal sign: look = it's funny

are allowed
