unsigned long int | cucul_utf8_to_utf32 (char const *, unsigned int *) |
Convert a UTF-8 character to UTF-32. | |
unsigned int | cucul_utf32_to_utf8 (char *, unsigned long int) |
Convert a UTF-32 character to UTF-8. | |
unsigned char | cucul_utf32_to_cp437 (unsigned long int) |
Convert a UTF-32 character to CP437. | |
unsigned long int | cucul_cp437_to_utf32 (unsigned char) |
Convert a CP437 character to UTF-32. | |
int | cucul_utf32_is_fullwidth (unsigned long int) |
Tell whether a UTF-32 character is fullwidth. |
unsigned long int cucul_utf8_to_utf32 | ( | char const * | s, | |
unsigned int * | read | |||
) |
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.
s | A string containing the UTF-8 character. | |
read | A pointer to an unsigned integer to store the number of bytes in the character, or NULL. |
unsigned int cucul_utf32_to_utf8 | ( | char * | buf, | |
unsigned long int | ch | |||
) |
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.
buf | A pointer to a character buffer where the UTF-8 sequence will be written. | |
ch | The UTF-32 character. |
unsigned char cucul_utf32_to_cp437 | ( | unsigned long int | ch | ) |
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.
ch | The UTF-32 character. |
unsigned long int cucul_cp437_to_utf32 | ( | unsigned char | ch | ) |
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.
ch | The CP437 character. |
int cucul_utf32_is_fullwidth | ( | unsigned long int | ch | ) |
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.
ch | The UTF-32 character. |
