What 옧 means
옧 is a Hangul block built from Korean letters. Hangul groups consonant and vowel letters, called jamo, into a block for each syllable: ㅇ begins this one, ㅗ is its vowel, and ㄳ is the final consonant pair. “OGS” is the technical Unicode name for that combination, not a translation.
Hangul, the Korean writing system, dates to the 15th century. 옧 follows its pattern of combining letters into syllable blocks; that date belongs to the script, not to a separate historical sign called 옧.
Technical and neutral; it identifies one exact Hangul syllable block.
