Mac OS X: Korean "Ga" Character Appears in a Square When Typing Hangul Text

While typing Korean text using the Hangul input method, you may see the Korean character "Ga" in a square when a syllable is incomplete or not an actual Korean word.
Mac OS X 10.3 Panther can display the full set of over 11,000 Korean characters using Unicode fonts. However, the system fonts in Mac OS X 10.3 and Mac OS X 10.2 do not include all extended Korean characters. Because of this, the Korean character "Ga" may sometimes appear in a square if you're using the Hangul input method.

This can happen when the Korean script is converted from the phonetic alphabet, or Jamo, to Hangul, which consists of clusters of Jamo characters. You may see Ga in a square when a cluster of Jamo characters is incomplete or does not yet create an actual Korean word. This occurs when the Jamo cluster is within the extended range and outside the standard range provided by the system font. Once the character cluster is completed, typed correctly, or another Jamo vowel is added for the next syllable, the text should display properly.

With Mac OS X 10.3, one workaround is to install a third-party Unicode font that includes the full set of Hangul syllables. For information about third-party font solutions, see the Apple Korea font list website (www.applecomputer.co.kr/hardware/fontlist.html) .
