RFR: 8351878: RichTextArea: Pasting from RTF doesn't apply formatting [v2]

[Andy Goryachev]

> Fixed two issues found in importing RTF text:
> 
> - charset translation (brought back removed code)
> - missing font size attribute
> - missing strike-through attribute
> 
> The charset issue was caused by my removal of the character decoder code present in the original JDK RTF parser/reader.  Why did I do that?
