void	pushChars (const char *str)

Detailed Description

A completely asynchronous implementation of a UTF8 encoder. Can work with the Print interface as it expects no end to the stream, and requires only a very simple change in the write function.

Constructor & Destructor Documentation

Utf8TextProcessor()

tccore::Utf8TextProcessor::Utf8TextProcessor ( UnicodeCharacterHandler  handler, void *  userData, UnicodeEncodingMode  mode  )

explicit

Create an instance of a UTF-8 decoder that will asynchronous process data calling the handler as characters are decoded from the stream.

Parameters

handler	the callback that receives characters
userData	an optional piece of data to pass back to you in the callback, can be nullptr
mode	processing mode, either ENCMODE_UTF8 or ENCMODE_EXT_ASCII

Member Function Documentation

pushChar()

void Utf8TextProcessor::pushChar

(

char

ch

)

Pushes a single character through the decoder. As characters are decoded the callback will fire.

Parameters

ch	the character to process

pushChars()

void Utf8TextProcessor::pushChars

(

const char *

str

)

Pushes a string of character data through the encoder. As characters are decoded the callback will fire.

Parameters

str	the string of data to process

reset()

void Utf8TextProcessor::reset

(

)

completely reset the decoder back to initial state
