Export encoding

[tibee]

It would be nice to support character encoding of the exported files.
For example. due to Excel's limitation, if I have accented characters in my utf-8 encoded darabase, like 'árvíztűrő tükörfúrógép', I need to convert it to iso-8859-2, to appear in Excel correctly. When opening utf-8 file, the accented characters break.

It occurs as CSV and as Excel too, so I would need to configure it to convert the rows to iso-8859-2 before export.

@tibee could you submit a PR for this?

@tibee:
I use the following steps to get the correct encodeing.

1. Export grid as CSV
2. Open an empty sheet in excel
3. On the Data tab, in the Get External Data group, click From Text.
4. Choose the exported *.csvfile
5. Select Tabbed and choose _60051 Uniform (UTF-8)_ encodeing on the opening window
6. After next select coma as delimiter
7. Finish
8. Enjoy the well formated characters 👍
