CJK compatibility ideograph U+FAB9

調 is a source-specific compatibility form of 調. 調 is a Chinese-origin character found in Chinese and Japanese writing and in Korean text written with Chinese characters. Depending on language and compound, it can mean adjusting, regulating, investigating, harmonizing, or musical tone.

The wider Han writing tradition is attested in oracle-bone inscriptions—writing carved on animal bones and turtle shells—from the 14th–11th centuries BCE. That history belongs to the character tradition, not to this exact compatibility form.

The source label is KP1-769A in KPS 10721-2000, a North Korean character standard. U+FAB9 preserves this source entry through Unicode conversion; it does not add a new meaning.

Why does 調 turn into 調?

Unicode normalization maps U+FAB9 to 調. Compatibility ideographs preserve correspondences with older character sets, so this code point records a source form rather than a separate dictionary meaning.

Unicode also defines 調︀—調 followed by variation selector 1, an extra character that requests a particular glyph in supporting fonts—as the standardized variation sequence for this form.

A font or text system without sequence support may show plain 調. That changes the glyph on screen, not the meaning.

How do I type 調?

A normal input method may produce 調 instead of 調.

In source code, use the Unicode escape \uFAB9 in a language that supports escapes, then prevent normalization if this source distinction must remain.

After normalization, use 調︀ (U+8ABF followed by U+FE00) when the receiving software and font support the sequence.
