stringprep_ucs4_nfkc_normalize - normalize Unicode string
- Parameters:
-
| str | a Unicode string. |
| len | length of array, or -1 if is nul-terminated. |
Converts UCS4 string into UTF-8 and runs
stringprep_utf8_nfkc_normalize().
Return value: a newly allocated Unicode string, that is the NFKC normalized form of .

stringprep_ucs4_to_utf8 - convert UCS-4 string to UTF-8
- Parameters:
-
| str | a UCS-4 encoded string |
| len | the maximum length of to use. If < 0, then the string is terminated with a 0 character. |
| items_read | location to store number of characters read read, or NULL. |
| items_written | location to store number of bytes written or NULL. The value here stored does not include the trailing 0 byte. |
Convert a string from a 32-bit fixed width representation as UCS-4. to UTF-8. The result will be terminated with a 0 byte.
Return value: a pointer to a newly allocated UTF-8 string. This value must be deallocated by the caller. If an error occurs, NULL will be returned and set.

stringprep_unichar_to_utf8 - convert Unicode code point to UTF-8
- Parameters:
-
| c | a ISO10646 character code |
| outbuf | output buffer, must have at least 6 bytes of space. If NULL, the length will be computed and returned and nothing will be written to . |
Converts a single character to UTF-8.
Return value: number of bytes written.

stringprep_utf8_nfkc_normalize - normalize Unicode string
- Parameters:
-
| str | a UTF-8 encoded string. |
| len | length of , in bytes, or -1 if is nul-terminated. |
Converts a string into canonical form, standardizing such issues as whether a character with an accent is represented as a base character and combining accent or as a single precomposed character.
The normalization mode is NFKC (ALL COMPOSE). It standardizes differences that do not affect the text content, such as the above-mentioned accent representation. It standardizes the "compatibility" characters in Unicode, such as SUPERSCRIPT THREE to the standard forms (in this case DIGIT THREE). Formatting information may be lost but for most text operations such characters should be considered the same. It returns a result with composed forms rather than a maximally decomposed form.
Return value: a newly allocated string, that is the NFKC normalized form of .

stringprep_utf8_to_ucs4 - convert UTF-8 string to UCS-4
- Parameters:
-
| str | a UTF-8 encoded string |
| len | the maximum length of to use. If < 0, then the string is nul-terminated. |
| items_written | location to store the number of characters in the result, or NULL. |
Convert a string from UTF-8 to a 32-bit fixed width representation as UCS-4, assuming valid UTF-8 input. This function does no error checking on the input.
Return value: a pointer to a newly allocated UCS-4 string. This value must be deallocated by the caller.

stringprep_utf8_to_unichar - convert UTF-8 to Unicode code point
- Parameters:
-
| p | a pointer to Unicode character encoded as UTF-8 |
Converts a sequence of bytes encoded as UTF-8 to a Unicode character. If
does
not point to a valid UTF-8 encoded character, results are undefined.
Return value: the resulting character.
