Syntax
Determines whether the given byte is a lead byte of a multi-byte character, and how many tail bytes follow.
When parsing a string in a host encoding, you must keep in mind that the string could be in a variable length multi-byte encoding. In such an encoding (for example, Shift-JIS) the number of bytes required to represent a character varies on a character-by-character basis. To parse such a string you must start at the beginning and, for each byte, determine whether that byte represents a character or is the first byte of a multi-byte character. If the byte is a lead byte for a multi-byte character, you must also compute how many bytes will follow the lead byte to make up the entire character. Currently the API provides a call (PDHostMBLen()) that performs these computations, but only if the encoding in question is the operating system encoding (as returned by PDGetHostEncoding()). ASHostMBLen() allows you to determine this for any byte in any host encoding.
Parameters
| encoding — | The host encoding type. |
| |
| byte — | The first byte of a multi-byte character. |
Returns
| The number of additional bytes required to form the character. For example, if the encoding is a double-byte encoding, the return value will be 1 for a two-byte character and 0 for a one-byte character. For Roman encodings, the return value will always be 0. |

Syntax
Tests whether the bytes in the string conform to the Unicode UTF-8 encoding form. The method does not test whether the string is NULL-terminated.
Parameters
| cIn — | The string. |
| |
| cInLen — | The length of the string in bytes, not including the NULL byte at the end. |
Returns
| true if the bytes in the string conform to the Unicode UTF-8 encoding form, false otherwise.
