(Command too long..See sample Output..)
curl doesn't provide url-encoding for 'GET' data, it have an option '--data-urlencode', but its only for 'POST' data. Thats why I need to write down this commandline. With 'perl', 'php' and 'python', this is one liner, but just I wrote it for fun. Works in Ubuntu, will work in all linux varients(I hope it will work in unix varients also).
Sample Output
$ sed -e's/./&\n/g' -e's/ /%20/g' | grep -v '^$' | while read CHAR; do test "${CHAR}" = "%20" && echo "${CHAR}" || echo "${CHAR}" | grep -E '[-[:alnum:]!*.'"'"'()]|\[|\]' || echo -n "${CHAR}" | od -t x1 | tr ' ' '\n' | grep '^[[:alnum:]]\{2\}$' | tr '[a-z]' '[A-Z]' | sed -e's/^/%/g'; done | sed -e's/%20/+/g' | tr -d '\n'; echo
