UTF-8 collation is based on the numeric representation of the character as opposed to the alphabetic order of the character.The start position should be an expression that evaluates to an integer. It specifies the offset from which the substring starts. The offset is measured in: The number of UTF-8 characters if the input is VARCHAR. The number of bytes if the input is BINARY.
