hanjadic is a program that displays Chinese-based Korean characters ("hanja"), their Korean pronunciations, Korean and English definitions, their radicals, and related Korean vocabulary derived from the Chinese. There are four ways to search in hanjadic: English, character sound, character compounds (words composed of multiple characters), and by character. Despite its name, it probably isn't that good as a dictionary and is better suited as a Korean etymology and vocabulary-building tool, though it is also designed to show the beauty of traditional Chinese characters.

No exception is thrown, but a message is added to the errors object of your model. This may then be used further on.
