thwchar_t th_macthai2uni

(

thchar_t

c

)

Convert character code from Mac Thai extended code to Unicode.

Parameters

c	: Mac Thai character/glyph to convert

Returns

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

wc

)

Convert character code from Unicode to Mac Thai extended code.

Parameters

wc	: Unicode code to convert

Returns

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

thchar_t th_uni2tis

(

thwchar_t

wc

)

Convert character code from Unicode to TIS-620.

Parameters

wc	: Unicode character to convert

Returns

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

int th_uni2tis_line	(	const thwchar_t *	s,
		thchar_t *	result,
		size_t	n
	)

Convert string from Unicode to TIS-620.

Parameters

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

Returns

the length of the output TIS-620 string

Note that, since the conversion is lossy, some characters in the convesion result may be TH_ERR, indicating conversion error.
