Utility functions to convert between UTF-8, full Unicode and Latin-1. Redland uses UTF-8 for all string formats (except where noted) but these may need to be converted to other Unicode encodings or downgraded with loss to Latin-1.
int librdf_unicode_char_to_utf8 (librdf_unichar c
,unsigned char *output
,int length
);
librdf_unicode_char_to_utf8
is deprecated and should not be used in newly-written code.
Convert a Unicode character to UTF-8 encoding.
deprecated
: Use raptor_unicode_utf8_string_put_char()
noting that
the length argument is a size_t.
If buffer is NULL, then will calculate the length rather than perform it. This can be used by the caller to allocate space and then re-call this function with the new buffer.
int librdf_utf8_to_unicode_char (librdf_unichar *output
,const unsigned char *input
,int length
);
librdf_utf8_to_unicode_char
is deprecated and should not be used in newly-written code.
Convert an UTF-8 encoded buffer to a Unicode character.
deprecated
: Use raptor_unicode_utf8_string_get_char()
noting that
the arg order has changed to input, length (a size_t), output.
If output
is NULL, then will calculate the number of bytes that
will be used from the input buffer and not perform the conversion.
unsigned char * librdf_utf8_to_latin1 (const unsigned char *input
,int length
,int *output_length
);
librdf_utf8_to_latin1
is deprecated and should not be used in newly-written code.
Convert a UTF-8 string to ISO Latin-1.
Converts the given UTF-8 string to the ISO Latin-1 subset of Unicode (characters 0x00-0xff), discarding any out of range characters.
deprecated
for librdf_utf8_to_latin1_2()
that takes and returns
size_t sizes and allows replacing of out of range characters.
If output_length
is not NULL, the returned string length
will be stored there.
unsigned char * librdf_utf8_to_latin1_2 (const unsigned char *input
,size_t length
,unsigned char discard
,size_t *output_length
);
Convert a UTF-8 string to ISO Latin-1.
Converts the given UTF-8 string to the ISO Latin-1 subset of
Unicode (characters 0x00-0xff). Out of range characters are
replaced with discard
unless it is NUL (\0).
If output_length
is not NULL, the returned string length will be
stored there.
unsigned char * librdf_latin1_to_utf8 (const unsigned char *input
,int length
,int *output_length
);
librdf_latin1_to_utf8
is deprecated and should not be used in newly-written code.
Convert an ISO Latin-1 encoded string to UTF-8.
Converts the given ISO Latin-1 string to an UTF-8 encoded string representing the same content. This is lossless.
deprecated
for librdf_latin1_to_utf8_2()
that takes and returns
size_t sizes.
If output_length
is not NULL, the returned string length will be
stored there.
unsigned char * librdf_latin1_to_utf8_2 (const unsigned char *input
,size_t length
,size_t *output_length
);
Convert an ISO Latin-1 encoded string to UTF-8.
Converts the given ISO Latin-1 string to an UTF-8 encoded string representing the same content. This is lossless.
If output_length
is not NULL, the returned string length will be
stored there.
