                int cur_c,
                byte[] src,
                int cur_pos)

Surrogate_split

public static void Surrogate_split(int v,
                   int[] ary)

                 int start,
                 int[] ch)

return one less than the number of bytes used by the UTF-8 byte sequence. The Unicode char is returned in ch.

Parameters:

str - points to the UTF-8 byte sequence

start - starting offset in str

ch - initialized to 1st byte, passed as an array to allow modification

Returns:

one less that the number of bytes used by UTF-8 char

putUTF8

public static int putUTF8(byte[] buf,
          int start,
          int c)

store char c as UTF-8 encoded byte stream.

Parameters:

buf -

start -

c -

Returns:

flushLine

                 int indent)

Parameters:
