CJK compatibility ideograph FA88

It is a compatibility form of 愈.

In Chinese, 愈 can mean “recover,” “surpass,” or “more and more.” Korean Hanja (Chinese characters used in Korean) reads it as 유, roughly “yoo,” with the meanings “recover or heal” and “increasingly.” Japanese dictionaries list kana readings (Japanese sound-writing) いえる and いやす for “recover” and “heal,” and いよいよ for “more and more” or “at last”; they also list ユ in compounds. Language and sentence decide the sense; 愈 adds no separate meaning.

愈 appears in classical Chinese texts including the Book of Songs, an early poetry collection, and Mencius, a philosophical text. 愈 is a later encoded form kept for back-and-forth conversion with KPS 10721-2000; its job is to preserve a distinction from the source.

Why does 愈 turn into 愈?

Normalization can map 愈 to 愈.

Unicode normalization treats them as canonically equivalent, so software may replace this compatibility character with 愈. When preserving the source glyph matters, the standardized variation sequence 愈︀ (U+6108 U+FE00) can request the FA88 display form in software that supports it.

Fonts determine which Han glyph appears. A font without FA88 may show a missing-glyph box; regional font fallback can show a different acceptable design. Neither changes the character’s meaning.
