Description

If the data that is being exported has non-standard ascii characters such as the Euro symbol or a bullet, the encoding in the CSV file displays them incorrectly. When I enable the 'exporterOlderExcelCompatibility' flag, the symbols are displayed correctly but I lose my newlines.

I created a plunkr to easily test these two use cases: http://plnkr.co/hn0WNVNOi9VIWsATdy0F

Research direction
Review the exporter module in ui grid, specifically the CSV generation logic. Examine the 'exporterOlderExcelCompatibility' flag handling in the source code. Use the provided plunkr to reproduce the issue. Look for how character encoding is handled (e.g., using TextEncoder or external libraries). Ensure that when the compatibility flag is true, newlines are preserved while special characters are encoded correctly.
