The '''Basic Latin''' [[Unicode block]],<ref>{{cite web|url=https://www.unicode.org/Public/UCD/latest/ucd/Blocks.txt|title=block.txt|accessdate=232023-03-202323|publisher=The Unicode Consortium}}</ref> sometimes informally called '''C0 Controls and Basic Latin''',<ref>{{cite web|url=https://www.unicode.org/charts/PDF/U0000.pdf|title=C0 Controls and Basic Latin|work=The Unicode Standard, Version 15.0|publisher=[[Unicode Consortium|Unicode, Inc.]]|year=2022|access-date=March 22, 2023}}</ref> is the first block of the [[Unicode]] standard, and the only block which is encoded in one byte in [[UTF-8]]. The block contains all the [[ISO basic Latin alphabet|letters]] and [[ASCII control character|control codes]] of the ASCII encoding. It ranges from U+0000 to U+007F, contains 128 characters and includes the [[C0 controls]], ASCII [[punctuation]] and [[symbol]]s, [[ASCII]] [[numerical digit|digits]], both the [[uppercase]] and [[lowercase]] of the [[English alphabet]] and a [[control character]].

The Basic Latin block was included in its present form from version 1.0.0 of the Unicode Standard, without addition or alteration of the character repertoire.<ref name=Unicode1.0>{{cite book|title=The Unicode Standard Version 1.0, Volume 1|year=1990|publisher=Addison-Wesley Publishing Company, Inc.|isbn=0-201-56788-1}}</ref> Its block name in Unicode 1.0 was '''ASCII'''.<ref>{{cite web |url=https://www.unicode.org/versions/Unicode1.0.0/CodeCharts2.pdf |work=The Unicode Standard |version=version 1.0 |title=3.8: Block-by-Block Charts |publisher=[[Unicode Consortium]]}}</ref>

===C0 controls===

The [[C0 and C1 control codes|C0 Controls]], referred to as C0 ASCII control codes in version 1.0, are inherited from ASCII and other 7-bit and 8-bit encoding schemes. The Alias names for C0 controls are taken from the [[ISO/IEC 6429|ISO/IEC 6429:1992]] standard.<ref name=charts />

===ASCII punctuation and symbols===
