What Is the Difference Between ANSI and UTF-8 URI Formats?

ANSI and UTF-8 are both encoding formats. ANSI is the common one byte format used to encode Latin alphabet; whereas, UTF-8 is a Unicode format of variable length (from 1 to 4 bytes) which can encode all possible characters.

By default, the Web Pages connector expects that addresses are in the ANSI format, but you can select the Use UTF-8 addresses option for a given source (see Modifying Advanced Source Parameters).

Note: When the Web Pages or the SharePoint connectors download web content, they expect documents with addresses encoded in UTF-8.
