When writing script code in Jython technology, specify any non-English strings in UNICODE by prefixing the letter “u” before the string in double quotes. This means instead of defining a string as "MyValue" define it as u"MyValue". See the following example used in data load mapping script for the Account dimension
The scripts above uses the “u”prefix for the user defined strings. You can optionally specify the u prefix for English/ASCII strings (that is, you can use "1110" or u"1110"). The following shows the result of the mapping applied on the workbench.
