SmartConnect by default has two character sets available, OEM, and ANSI. Neither of these include the special characters used in non-English languages such as ñ, á, ü. The work around is to edit the SmartConnect SchemaHeader table to inform the ODBC driver to use the UTF-8 character set.
1. Create and save a map like normal, selecting ANSI as the Character Set when creating the schema file
2. Edit the SmartConnect SchemaHeader table to use Character set ‘65001’
Set CharacterSet = ‘65001’
WHERE SchemaHeaderId = ‘UTF8_TEXT_TT_SAMPLE__spanishText_csv’
3. Reopen the map and preview the data source
