0x1C

0x1C is a hexadecimal literal representing the decimal value 28. In many programming and computing contexts, it is used as a numeric constant or as part of bitwise operations.

In ASCII and Unicode, 0x1C corresponds to the control character known as the File Separator (FS). It is a non-printable C0 control code and has the Unicode code point U+001C. As a control character, it does not have a visible glyph in standard text rendering, and its handling is typically left to software that processes control codes rather than displays them.

Historically, FS was used to separate records or fields within data streams and telecommunications protocols. In modern text files and user interfaces, it seldom appears as a visible character; many systems treat it as a control value used to structure or delimit data rather than as a printable symbol.

In programming, 0x1C appears as a hex constant and can be combined with other values in bitwise operations. Its binary form is 0001 1100, which makes it useful for masking or extracting specific bits (for example, bits 2 through 4) within a byte when needed in low-level data processing or hardware interfacing.

Related concepts include other C0 control codes (ranging from 0x00 to 0x1F) and the various encoding schemes that map these control characters to their numerical values. The interpretation of 0x1C can vary by context, particularly between raw binary data, text processing, and protocol design.
