U014C

U+014C is the Unicode code point for the LATIN CAPITAL LETTER O WITH MACRON. It is part of the Latin Extended-A block and is categorized as an uppercase letter ( Lu ). Its lowercase counterpart is LATIN SMALL LETTER O WITH MACRON (U+014D), and the precomposed character is used in several orthographies to represent a long vowel.

The macron, a horizontal bar diacritic placed above the letter, signals vowel length in various languages and transcription schemes. In practice, Ō corresponds to a long o sound in languages such as Māori and in some transliteration systems for Japanese and other languages. The letter remains distinct from other O-based letters with diacritics (for example Ó or Ô), which indicate different phonetic values.

Encoding and representation: in UTF-8, U+014C encodes as the two-byte sequence C5 8C. In UTF-16, it is represented as 0x014C. In HTML, it can be written using the named entity Ō or the numeric references Ō or Ō (decimal).

Usage notes: as a precomposed character, U+014C is frequently used in proper names, loanwords, and scholarly transcriptions that require precise vowel length. Some systems also decompose it into a base letter O plus a combining macron, depending on font and rendering support.
