For delimited flat files, data precision is measured in characters. When you insert multibyte character data in the target, you do not need to allow for additional precision for multibyte data. Sybase IQ does not allow optional quotation marks. You must choose None for Optional Quotes if you have a delimited target flat file.
When you load multibyte data to Sybase IQ, null characters and delimiters can be up to four bytes each. To avoid reading the delimiter as a regular character, each byte of the delimiter must have an ASCII value of less than 0x40.
