Function ideograph_name

pub fn ideograph_name(cp: u32) -> Option<String>

Return the character name of the given ideograph codepoint.

This operation is only defined on ideographic codepoints. This includes precisely the following inclusive ranges:

• 3400..4DB5
• 4E00..9FD5
• 20000..2A6D6
• 2A700..2B734
• 2B740..2B81D
• 2B820..2CEA1
• 17000..187EC
• F900..FA6D
• FA70..FAD9
• 2F800..2FA1D

If the given codepoint is not in any of the above ranges, then None is returned.

This implements the algorithm described in Unicode 4.8.
