A client of mine was having problems with some multibyte characters turning html emails into a corrupted mess - especially on mobile devices. This vQmod base encodes the html email which solved our problem and seems to keep everything consistently intact during mail transfer. Tested on 1.5.6.1+:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

			<search position="replace"><![CDATA[$this->html = $html;]]></search>
			<add><![CDATA[$this->html = chunk_split(base64_encode($html));]]></add>
		</operation>
		<operation>
			<search position="replace" index="3"><![CDATA[8bit]]></search>
			<add><![CDATA[base64]]></add>
		</operation>
	</file>
