public class UCSReader
Reader for UCS-2 and UCS-4 encodings. (i.e., encodings from ISO-10646-UCS-(2|4)).
| Field Summary | |
|---|---|
static int |
DEFAULT_BUFFER_SIZE
Default byte buffer size (8192, larger than that of ASCIIReader since it's reasonable to surmise that the average UCS-4-encoded file should be 4 times as large as the average ASCII-encoded file). |

fBuffer
Byte buffer. |
