Detailed Description

Wide char support for Thai.

Function Documentation

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.

thchar_t th_uni2winthai (thwchar_t wc)

Convert character code from Unicode to Thai Windows extended code. Parameters:

wc : Unicode code to convert

Returns:

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

thwchar_t th_winthai2uni (thchar_t c)

Convert character code from Thai Windows extended code to Unicode. Parameters:

c : Thai Windows character/glyph to convert

Returns:

Corresponding Unicode code
