| Unicode number | U+0001 | |
| Category | ASCII Table1. ASCII control characters | |
| Description | The Unicode character , or U+0001, is known as the "Start of Heading". It falls under the "C0 Controls and Basic Latin" block and the "Control" category in the Unicode standard. This character is part of a series of control codes that were first defined in the American Standard Code for Information Interchange (ASCII). The Start of Heading character was originally intended to be used in text-based data transmission systems (like teletypes) to signify the beginning of a sequence of characters that constitute a machine-readable "heading" or label for the message that follows. However, in most modern applications, these control characters are not commonly used. |
