Corresponding Unicode code

thwchar_t th_tis2uni

(

thchar_t

c

)

Convert character code from TIS-620 to Unicode.

Parameters:

c

: TIS-620 character to convert

Returns:

Corresponding Unicode code

int th_tis2uni_line	(	const thchar_t *	s,
		thwchar_t *	result,
		size_t	n
	)

Convert string from TIS-620 to Unicode.

Parameters:

	s	: source TIS-620 string (null-terminated)
	result	: buffer for storing resulting Unicode string
	n	: size of result buffer (as number of elements)

Returns:

the length of the output Unicode string

thchar_t th_uni2macthai

(

thwchar_t

c

)

Convert character code from Unicode to Mac Thai extended code.

Parameters:

c

: Unicode code to convert

Returns:

Corresponding Mac Thai extended code, or TH_ERR if conversion is impossible

thchar_t th_uni2tis

thwchar_t

c

)

Convert character code from Unicode to TIS-620.

Parameters:

c

: Unicode character to convert

Returns:

Corresponding TIS-620 code, or TH_ERR if conversion is impossible

int th_uni2tis_line	(	const thwchar_t *	s,
