Spurious blanks shown for non-BMP Unicode

Hi,

for characters from Unicode planes 1..16, e.g. U+1D6DF (Math bold Phi), PSPad shows an additional space character. Deleting such a space/blank, destroys the character.

The characters are represented by surrogate pairs in UTF-16.

P.S.: In my initial post, I had such characters ready for copy/paste, but the forum didn't accept it (silently) although "preview" worked.
