Abstract

A method is for input of text symbols into an electronic device having a reduced keyboard. The reduced keyboard has keys representing a plurality of characters. The method includes receiving character inputs from the reduced keyboard and identifying symbol variants based on the received character inputs. A list of symbol variants is displayed. An input symbol from the list of symbol variants is selected, wherein the input symbol is a Korean Hangul syllable. At least one Chinese Hanzi syllable is designated, to correspond to at least one Korean Hangul syllable. The Korean Hangul syllable is replaced with a Chinese Hanzi syllable.

Claims

displaying a list of symbol variants;

selecting an input symbol from the list of symbol variants, wherein the input symbol is a Korean Hangul syllable;

designating at least one Chinese Hanzi syllable to correspond to at least one Korean Hangul syllable; and

replacing the Korean Hangul syllable with a Chinese Hanzi syllable.
