CJK Compatibility Ideograph FA1C

靖 is the legacy glyph form of 靖. Depending on its Chinese or Japanese word, 靖 can mean calm, peaceful, or to pacify; 靖 does not add a separate meaning. For ordinary writing in either language, 靖 is the usual form.

The Shuowen Jiezi, an old Chinese character dictionary, records a seal-script form of 靖, an ancient Chinese writing style, and analyzes it as 立 («stand») plus 青, a component that supplies the sound.

In 1993, 靖 entered the IBM-Kanji compatibility set in ISO/IEC 10646-1. This let conversions between IBM and Microsoft Japanese encodings preserve the original character and restore it when converted back. The date belongs to the computer encoding, not to the history of 靖.

why does 靖 turn into 靖?

Unicode normalization can replace it with 靖. Unicode treats the pair as canonically equivalent, so all four standard forms—NFC, NFD, NFKC, and NFKD—can map 靖 to 靖.

Unicode defines 靖 followed by U+FE00 (Variation Selector-1) as the standardized variation sequence for requesting this glyph. Use the sequence when the distinction must survive text processing; the app and font must support it.

why does 靖 look different in my font?

The font and text system determine the Han glyph shape. Unicode's sample glyph does not require every font to draw it the same way.

A font or text system without this glyph or variation sequence may show the ordinary 靖 form or ignore the selector. That changes the appearance, not the text's original character identity. Compare the code points before treating a visual difference as a change in meaning.
