NAME

src/encodings/utf16.c - UTF-16 encoding

DESCRIPTION

UTF-16 encoding with the help of the ICU library.

Functions

static STRING *to_encoding

Converts the string src to this particular encoding. If dest is provided, it will contain the result. Otherwise this function operates in place.

static UINTVAL get_codepoint

Returns the codepoint in string src at position offset.

static void set_codepoint

Sets, in string src at position offset, the codepoint codepoint.

static UINTVAL get_byte

Returns the byte in string src at position offset.

static void set_byte

Sets, in string src at position offset, the byte byte.

static STRING *get_codepoints

Returns the codepoints in string src at position offset and length count.

static STRING *get_codepoints_inplace

Gets from string src at position offset count codepoints and returns them in return_string.

static STRING *get_bytes

Returns the bytes in string src at position offset and length count.

static STRING *get_bytes_inplace

Gets from string src at position offset count bytes and returns them in return_string.

static void set_codepoints

Replaces in string src at position offset for count codepoints with the contents of string new_codepoints.

static void set_bytes

Replaces in string src at position offset for count bytes with the contents of string new_bytes.

static void become_encoding

Unconditionally makes the string be in this encoding, if that's valid

static UINTVAL codepoints

Returns the number of codepoints in string src.

static UINTVAL bytes

Returns the number of bytes in string src.

static UINTVAL utf16_decode_and_advance

Moves the string iterator i to the next UTF-16 codepoint.

static void utf16_encode_and_advance

With the string iterator i, appends the codepoint c and advances to the next position in the string.

static void utf16_set_position

Moves the string iterator i to the position n in the string.

static void iter_init

Initializes for string src the string iterator iter.

ENCODING *Parrot_encoding_utf16_init

Initializes the UTF-16 encoding.
