What 洞 means
Read it as 洞, the Han character for a cave or hole.
Unicode maps this form to 洞 and records source position K0-7753 in the Korean KS C 5601-1987 character set. Its Hanja repertoire—Chinese characters used in Korean—kept duplicate positions for alternate pronunciations and round-trip conversion with older encodings. This code point preserves that source trail; it does not mark the origin of 洞.
Why does 洞 turn into 洞?
Compatibility normalization maps 洞 to 洞.
The NFKC and NFKD forms apply compatibility mappings; NFC and NFD leave this distinction intact. Use 洞 for new text unless you are preserving data from that legacy Korean character position.
How do I type 洞 exactly?
Enter FA05 as a Unicode code point.
Selecting 洞 in a Han-character input method gives the unified form. In software or an input method that accepts hexadecimal Unicode entry, enter FA05 to request this exact form.
Archival and technical: it marks preservation of a legacy source distinction.
Do not use it as decoration for 洞; compatibility normalization can erase the distinction.
