I have customers that are using special characters - mainly "easter eggs" these days  - and would like to store these fields in a multiline text field or a rich text field. I cannot store these special characters and get an Internal error (for the incorrect string value I presume, because if I remove the icon all goes well). 

Any tips here for light-weight solutions? I am now regex_replacing at strategic locations and have considered base64 string storage but it all feels a bit cumbersome. All tips are welcome :-)
