  • This one uses hex conversion to do the converting and is in shell/sed only (should probably still use the python/perl version).

  • It only encodes non-Basic-ASCII chars, as they are the only ones not well readed by UTF-8 and ISO-8859-1 (latin-1). It converts all * C3 X (some latin symbols like ASCII-extended ones) and * C2 X (some punctuation symbols like inverted exclamation) ...UTF-8 double byte symbols to escaped form that every parser understands to form the URLs. I didn't encode spaces and the rest of basic punctuation, but supposedly, space and others are coded as \x20, for example, in UTF-8, latin-1 and Windows-cp1252.... so its read perfectly. Please feel free to correct, the application to which I designe that function works as expected with my assumption. Note: I specify a w=999, I didn't find a flag to put unlimited value. I just suppose very improbable surpass the de-facto 255 (* 3 byte max) = 765 bytes length of URL Show Sample Output


    1
    od -An -w999 -t xC <<< "$1" | sed 's/[ ]\?\(c[23]\) \(..\)/%\1%\2/g;s/ /\\\\\x/g' | xargs echo -ne

python version left the "/" char unconverted to me; I had to add "| sed 's/\//%2F/g' " at the end of the line
