0x043F

0x043F is the hexadecimal notation for a Unicode code point used in computing. It corresponds to U+043F, the Cyrillic small letter PE. The character is written as 'п' and represents the voiceless bilabial plosive sound "p" in languages that use the Cyrillic script, most notably Russian, Ukrainian, and Bulgarian, among others. The Cyrillic block in Unicode runs from U+0400 to U+04FF, with U+043F occupying the lowercase letter section.

In terms of encoding, U+043F is represented as follows: in UTF-8 it is encoded as the two-byte sequence 0xD0 0xBF; in UTF-16 it is 0x043F; and in UTF-32 it is 0x0000043F. These encodings allow the character to be stored and transmitted in different text formats and environments.

In HTML and other markup contexts, the Cyrillic small letter PE can be referenced numerically as п (hex) or п (decimal). This provides a way to include the character in documents without relying on specific font support.

Notes and context: while 0x043F is a common hexadecimal representation encountered in programming, the authoritative Unicode reference uses the code point U+043F and the character name CYRILLIC SMALL LETTER PE. The character is a standard component of the Cyrillic script used across a range of Slavic and non-Slavic languages.
