CJK compatibility ideograph F9FB

It represents 炙, a Han character meaning roast or broil.

炙 is a Han character from the Chinese writing tradition. The Shuowen Jiezi, an early Chinese character dictionary, defines it through roasting meat. A Taiwanese character-variant dictionary also records an older 籀文 form, a named historical script style. That history belongs to 炙; 炙 is a later encoding form.

In Korean Hanja, the character has readings 자 and 적. The 적 reading expanded from food cooked over fire to skewered, seasoned dishes; Korean cultural references connect that culinary line to maekjeok (맥적), an older Korean grilled-meat tradition. Japanese references also record roast or broil and, in compounds, be familiar with.

Why does it have a separate Unicode code point?

It preserves an encoding distinction, not a new meaning.

F9FB comes from the Korean character-set standards KS C 5601 and KS X 1001. They assigned separate codes to some Hanja forms to preserve reading distinctions; Unicode retained this one for round-trip conversion, which lets data return to its source encoding without losing that distinction.

Unicode compatibility normalization, NFKC, folds compatibility Han ideographs into their unified counterparts. After it runs, text may contain the mapped character instead of this compatibility form: the meaning survives, but the distinct code-point identity does not. Preserve the unnormalized source when archival fidelity matters.
