Method Detail

Utf8ToString

public static java.lang.String Utf8ToString(byte[] src)

Converts an array of characters in UTF-8 format to a Unicode string.

Parameters:

src - Source string, in UTF-8 format.

Returns:

The translated string.

Utf8ToUtf16Char

public static int Utf8ToUtf16Char(java.io.InputStream src)

Returns a single UTF-16 character by reading as many characters as necessary from a given InputStream, which is a stream of UTF-8 bytes.

Parameters:

src - Source stream, in UTF-8 format.

Returns:

The next character constructed from the stream, -1 if no more.

Utf8ToUtf16

public static int Utf8ToUtf16(byte[] src,
                              char[] dst)

Converts an array of characters in UTF-8 format to an array of UTF-16/Unicode characters.

Parameters:

src - Source string, in UTF-8 format.

dst - Output buffer for unicode characters.

Returns:

The number of characters written. If dst is null, then only returns the number of chars needed.

StringToUtf8

public static byte[] StringToUtf8(java.lang.String src)

Converts a string to an array of UTF-8 characters.

Parameters:

src - Source string.

Returns:

The translated array of characters in UTF-8 format.

Utf16ToUtf8

public static int Utf16ToUtf8(char[] src,
                              byte[] dst)

Converts an array of characters in UTF-16/Unicode format to an array of characters in UTF-8 characters.

Parameters:

src - Source string, in unicode format.

dst - Output buffer for utf-8 characters.

Returns:

The number of bytes written. If dst is null, then only returns the number of bytes needed.
