10.6.16 CharTypeAt
CharTypeAt is similar to ByteTypeAt in that it tests the type of byte in a string at a given index. This allows a string to be tested for DBCS and SBCS information. The difference is that it only ever returns SBCS and DBCS. Possible results are:
SBCS - Single byte character
DBCS - Double byte character
Input Parameters
Index - Byte position within the supplied string
Example
If (#String.CharTypeAt( 1 ) = DBCS)
