U+F91F "蘭" CJK Compatibility Ideograph-# Unicode Character

U+F91F "蘭" CJK Compatibility Ideograph-# is a compatibility ideograph in the CJK (Chinese, Japanese, and Korean) Unicode block, specifically representing the character for "orchid." It is part of the compatibility ideographs section, which was included to support round trip conversion between older character set standards, such as CNS 11643 in Taiwan, and the Unicode standard. The character "蘭" is visually identical or very similar to the regular CJK Unified Ideograph for "orchid" (U+862D "蘭") but is encoded separately to preserve the exact mapping from the original standard. Its use is primarily historical and for maintaining data fidelity, as modern text systems typically prefer the unified version of the character.
