Japanese characters in R

Description

The implementation of Hershey vector fonts provides a large number of Japanese characters (Hiragana, Katakana, and Kanji).

Details

Without keyboard support for typing Japanese characters, the only way to produce these characters is to use special escape sequences: see Hershey.

For example, the Hiragana character for the sound ‘ka’ is produced by ‘⁠\\#J242b⁠’ and the Katakana character for this sound is produced by ‘⁠\\#J252b⁠’. The Kanji ideograph for "one" is produced by ‘⁠\\#J306c⁠’ or ‘⁠\\#N0001⁠’.

The output from demo(Japanese) shows tables of the escape sequences for the available Japanese characters.
