# Title : urlencode - encode URL data

# Description
# Encode data according to
# RFC 1738: "Uniform Resource Locators (URL)" and
# RFC 1866: "Hypertext Markup Language - 2.0" (HTML)
#
# This encoding is used i.e. for the MIME type
# "application/x-www-form-urlencoded"
#
# Notes
# o The default behaviour is not to encode the line endings. This
# may not be what was intended, because the result will be
# multiple lines of output (which cannot be used in an URL or a
# HTTP "POST" request). If the desired output should be one
# line, use the "-l" option.
#
# o The "-l" option assumes, that the end-of-line is denoted by
# the character LF (ASCII 10). This is not true for Windows or
# Mac systems, where the end of a line is denoted by the two
# characters CR LF (ASCII 13 10).
# We use this for symmetry; data processed in the following way:
# cat | urlencode -l | urldecode -l
# should (and will) result in the original data
#
# o Large lines (or binary files) will break many AWK
# implementations. If you get the message
# awk: record `...' too long
# record number xxx
# consider using GNU AWK (gawk).
#
# o urlencode will always terminate it's output with an EOL
# character
#
# Thanks to Stefan Brozinski for pointing out a bug related to non-standard
# locales.
