encode_utf8()

MAYAFLUX_API std::string MayaFlux::Portal::Text::encode_utf8

(

uint32_t

codepoint

)

Encode a Unicode codepoint as a UTF-8 byte sequence.

Counterpart to the decode step lay_out() performs via utf8proc_iterate. Invalid codepoints (surrogates, > 0x10FFFF) return an empty string.

Parameters

codepoint

Unicode codepoint to encode.

Returns

1-4 byte UTF-8 sequence, or empty on invalid input.
