Pasting with multicolored background text doesn't work right

[abdu 46]

I am copying text from a Windows app (RegexMagic) and the text has several background colors for the characters.. Meaning one character has one background color, the next character has a different background color.

When I try to paste this text, the text is modified, There are extra spaces and the dot h=which was in there is removed. The two paste options paste the same wrong text. Seems like a bug to me. The text is a regex expression. 

I have to paste in a text editor first to remove the formatting then copy from there and paste in Evernote.

It may have to do with the format of the material that is placed on the clipboard from RegexMagic. Do you know if it is HTML, RTF, etc.?
