Editing Email (section)

====Content encoding====
Internet email was designed for 7-bit ASCII.<ref>{{cite book|title=TCP/IP Network Administration|year=2002|isbn=978-0-596-00297-8|author=Craig Hunt|publisher=[[O'Reilly Media]]|page=70}}</ref> Most email software is [[8-bit clean]], but must assume it will communicate with 7-bit servers and mail readers. The [[MIME]] standard introduced character set specifiers and two content transfer encodings to enable transmission of non-ASCII data: [[quoted printable]] for mostly 7-bit content with a few characters outside that range and [[base64]] for arbitrary binary data. The [[8BITMIME]] and [[BINARY]] extensions were introduced to allow transmission of mail without the need for these encodings, but many [[mail transport agent]]s may not support them. In some countries, e-mail software violates {{IETF RFC|5322}} by sending raw<ref group=nb>Not using Internationalized Email or MIME</ref> non-ASCII text and several encoding schemes co-exist; as a result, by default, the message in a non-Latin alphabet language appears in non-readable form (the only exception is a coincidence if the sender and receiver use the same encoding scheme). Therefore, for international [[character set]]s, [[Unicode]] is growing in popularity.<ref>{{Cite web|title=What is unicode? |url=https://www.konfinity.com/what-is-unicode|access-date=2022-01-31|website=Konfinity |archive-date=January 31, 2022|archive-url=https://web.archive.org/web/20220131083432/https://www.konfinity.com/what-is-unicode|url-status=live}}</ref>
