Transactions CSV download not properly formatted

[hamaryns]

1. Download financial transactions as CSV
2. Open it with LibreOffice
3. Select comma as tabulator

• comments that contain a comma are split into two cells

• amounts are split into two cells (may be dependent on language setting: if amounts are formatted with comma rather than dot) and amounts above 1000 contain a ?
• non-ASCII symbols are not recognized (see screenshot)

The export algorithm should detect commas and put that string between quotes.
