Editing Vietnamese Quoted-Readable (section)

== Software support ==
VIQR is primarily used as a Vietnamese [[input method]] in software that supports [[Unicode]]. Similar input methods include [[Telex (IME)|Telex]] and [[VNI]]. Input method editors such as [[VPSKeys]] convert VIQR sequences to Unicode [[precomposed character]]s as one types, typically allowing modifier keys to be input after all the base letters of each word. However, in the absence of input method software or Unicode support, VIQR can still be input using a standard keyboard and read as plain ASCII text without suffering from ''[[mojibake]]''.

Unlike the [[Vietnamese Standard Code for Information Interchange|VISCII]] and [[VPS font|VPS]] code pages, VIQR is rarely used as a character encoding. While VIQR is registered with the [[Internet Assigned Numbers Authority]] as a [[MIME]] ''charset'', MIME-compliant software is not required to support it.<ref>RFC 1456.</ref> Nevertheless, the Mozilla Vietnamese Enabling Project once produced builds of the open source version of [[Netscape Communicator]], as well as its successor, the [[Mozilla Application Suite]], that were capable of decoding VIQR-encoded webpages, e-mails, and newsgroup messages. In these unofficial builds, a "VIQR" option appears in the Edit | Character Set menu, alongside the VISCII, [[TCVN 5712]], VPS, and [[Windows-1258]] options that remained available for several years in [[Firefox|Mozilla Firefox]] and [[Mozilla Thunderbird|Thunderbird]].<ref>{{cite web|title=Mozilla Vietnamese Enabling Project|publisher=Văn Lang Vietnamese Language & Culture Education Center|url=http://www.vnet.org/vanlangsj/mozilla/}}</ref><ref name="Van D.
