I think we can replace this
```
# strings start with index 1
idx=1
# lt: skip line break at end
while [ $idx -lt "$length" ]; do
char=$( printf "%s" "$str" | cut -c $idx )
h=$(( ( h * 31 + $(LC_CTYPE=C printf %d "'$char") ) % 4294967296 ))
idx=$(( idx + 1 ))
done
```
with this:
```
while [ "$str" != "" ]; do
char="${str%${str#?}}"
h=$(( ( h * 31 + $(LC_CTYPE=C printf %d "'$char") ) % 4294967296 ))
str="${T#?}"
done
```
