Can't get any hits in KB or forums for "double byte" (any variation), so posting this question:
Our team occasionally needs to export a Marketo smart list that contains double-byte characters. The character set is correct in Marketo. And in most cases, the double-byte characters come through correctly when the export is opened in Excel. But some characters are garbled, and we can't detect where the issue is occurring and how to solve it. Any advice?
