Beware: word splitting will be done here when expanding ${endchars}
because the " before it closes the first "
You should quote the inner ":
echo "before if, endchars = \"${endchars}\"."
> if ! [ -z $endchars ]; then
Beware: this will raise an error: [: ...: binary operator expected
if endchars contains spaces.
Quote $endchars:
if ! [ -z "$endchars" ]; then

Same remark than above for endchars.
