deurlname froms renameutils renames files properly, though it ignores %xy in folder path.

But so far I have found no function that works on strings in Bash script.

What I have tried so far:

1.

shopt -s expand_aliases
alias urldecodePython='python3 -c "import sys, urllib.parse as ul; print(ul.unquote_plus(sys.argv[1]))"'
fnonly=$( urldecodePython "$fnonly" )
urldecode() {
    # urldecode <string> ,  assumes the data contains no backslash.

    local url_encoded="${1//+/ }"
    printf '%b' "${url_encoded//%/\\x}"
}
fnonly="$(urldecode "$fnonly")"
fnonly=$(echo "$fnonly" | sed -e's/%\([0-9A-F][0-9A-F]\)/\\\\\x\1/g')
rename 'use URI::Escape; $_ = uri_unescape $_' $fdir/*%*

(Before I switched to deurlname; not a string function but had the same problem.)
