KnockType is based on the concept of braille notation in Japanese. It does not support braille notation in other languages.

KnockType is not necessarily aimed at facilitating "braille transcription". It is designed so that someone who understands the grammar of "braille transcription" can instantly transliterate into braille text that was previously transcribed to kana characters, etc. In addition, it allows ink characters to be converted to braille using OpenType features. It is recommended for use in applications that are compatible with OpenType features. If they are not compatible, KnockType is "simply a kana font". To be a little more specific, it is assumed that KnockType will be used in Adobe's InDesign and Illustrator applications. If you don't have them, you will not get satisfactory results.

Four types of font are available. There are "hasBox&Line", "hasnotBox&Line", and the reversed font of each. When displayed on a convex surface, the assumption is that they will be used mainly for printing applications. When displayed on a concave surface, the assumption is that they will be used mainly for writing on braille boards, etc. By printing, you can get a rough idea of the dot positions. It is more effective to match them to the grid size of the braille board.
