Convert a UTF-32 character to ASCII.
__extern int caca_utf32_is_fullwidth (uint32_t)
Tell whether a UTF-32 character is fullwidth.
Detailed Description
These functions perform conversions between usual character sets.
Function Documentation
__extern uint32_t caca_utf8_to_utf32 (char const *s, size_t *bytes) Convert a UTF-8 character read from a string and return its value in the
UTF-32 character set. If the second argument is not null, the total number of read bytes is written in it.
If a null byte was reached before the expected end of the UTF-8 sequence, this function returns zero and the number of read bytes is set to
zero.
This function never fails, but its behaviour with illegal UTF-8 sequences is undefined.
Parameters:
s A string containing the UTF-8 character.
bytes A pointer to a size_t to store the number of bytes in the character, or NULL.
Returns:
The corresponding UTF-32 character, or zero if the character is incomplete.
Referenced by caca_put_str().
__extern size_t caca_utf32_to_utf8 (char *buf, uint32_tch) Convert a UTF-32 character read from a string and write its value in the UTF-8
character set into the given buffer.
This function never fails, but its behaviour with illegal UTF-32 characters is undefined.
Parameters:
buf A pointer to a character buffer where the UTF-8 sequence will be written.
ch The UTF-32 character.
Returns:
The number of bytes written.
__extern uint8_t caca_utf32_to_cp437 (uint32_tch) Convert a UTF-32 character read from a string and return its value in the CP437 character
set, or '?' if the character has no equivalent.
This function never fails.
Parameters:
ch The UTF-32 character.
Returns:
The corresponding CP437 character, or '?' if not representable.
__extern uint32_t caca_cp437_to_utf32 (uint8_tch) Convert a CP437 character read from a string and return its value in the UTF-32 character
set, or zero if the character is a CP437 control character.
This function never fails.
Parameters:
ch The CP437 character.
Returns:
The corresponding UTF-32 character, or zero if not representable.
__extern char caca_utf32_to_ascii (uint32_tch) Convert a UTF-32 character into an ASCII character. When no equivalent exists, a graphically
close equivalent is sought.
This function never fails, but its behaviour with illegal UTF-32 characters is undefined.
Parameters:
ch The UTF-32 character.
Returns:
The corresponding ASCII character, or a graphically close equivalent if found, or '?' if not representable.
__extern int caca_utf32_is_fullwidth (uint32_tch) Check whether the given UTF-32 character should be printed at twice the normal width
(fullwidth characters). If the character is unknown or if its status cannot be decided, it is treated as a standard-width character.
This function never fails.
Parameters:
ch The UTF-32 character.
Returns:
1 if the character is fullwidth, 0 otherwise.
