hugowetterberg / ical-RFC-2445-4.1.php

Last active March 6, 2024 18:28

A useful function for splitting ical content into 75-octet lines, taking multibyte characters into account. See: http://www.ietf.org/rfc/rfc2445.txt, section 4.1

	<?php
	mb_internal_encoding("UTF-8");
	$desc = <<<TEXT
	<p>Lines of text SHOULD NOT be longer than 75 octets, (och hör på den) excluding the line break. Long content lines SHOULD be split into a multiple line representations using a line "folding" technique.</p>

	That is, a long line can be split between any two characters by inserting a CRLF
	immediately followed by a single linear white space character (i.e.,
	SPACE, <b>US-ASCII</b> decimal 32 or HTAB, US-ASCII decimal 9). Any sequence
	of CRLF followed immediately by a single linear white space character
	is ignored (i.e., removed) when processing the content type.
