## 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
