0x213B

0x213B is a hexadecimal numeral commonly encountered in computing. The prefix 0x indicates that the following digits are in base-16. The value 0x213B equals 8507 in decimal. In software development, such literals are used to specify constants, addresses, bitmasks, or identifiers in source code and configuration data. Its interpretation depends on context, such as the data type, endianness, and the surrounding system.

If interpreted as a Unicode code point, U+213B resides in the Letterlike Symbols block (range U+2100 to U+214F). The exact glyph associated with this code point depends on font rendering, and characters in this block are specialized mathematical or typographic symbols rather than standard alphanumeric characters. Many fonts do not render all code points in this range, and some environments may not display them at all.

In hardware and networking, 0x213B could serve as an address, port qualifier, or identifier within a protocol or device register map, but there is no universal meaning attached to this hexadecimal value by standards bodies. It is primarily meaningful when assigned by software, firmware, or a specification.

Examples: in C-like languages, you might see int x = 0x213B; in debugging logs, 0x213B could appear as a memory address offset or a flag value.
