| /** |
| * The CONSTANT_Utf8_info structure is used to represent constant string values.<P> |
| * |
| * The bytes of multibyte characters are stored in the class file in big-endian |
| * (high byte first) order. There are two differences between this format and the |
| * "standard" UTF-8 format. First, the null byte (byte)0 is encoded using the |
| * two-byte format rather than the one-byte format, so that Java Virtual Machine |
| * UTF-8 strings never have embedded nulls. Second, only the one-byte, two-byte, |
| * and three-byte formats are used. The Java Virtual Machine does not recognize |
| * the longer UTF-8 formats. |
