1. A character recognition apparatus comprising: an evaluation-value output unit that outputs a plurality of evaluation values for each of a plurality of character recognition programs which are different from each other, each of the plurality of evaluation values indicating a degree to which a character pattern which has been input corresponds to each of a plurality of character codes to be recognized using the character recognition program; a generation unit that generates feature information for the character pattern which has been input, the feature information including, as elements, the plurality of evaluation values being output by the evaluation-value output unit; a learning unit that learns classifications for feature information on a character-code-by-character-code basis on the basis of feature information generated by the generation unit for a character pattern for which a character code is specified in advance; and a determination unit that determines a character code of an unknown character pattern on the basis of which classification among the learned classifications for feature information on a character-code-by-character-code basis includes feature information generated by the generation unit for the unknown character pattern, the unknown character pattern being a character pattern whose character code is unknown.
