Press Version shows glyphs that are not defined in my character encoding.

If I use the default character encoding then char 128 shows as the Euro symbol. This is correct.

I switch to Iso-8859-4 (Latin 4) and char 128 now shows as not-defined. This is correct.

I then edit the encoding, based on Latin 4, to replace one glyph (any glyph, it doesn't matter which). Now char 128 shows as Euro again on the workspace view and preview. This is not correct.

Checking the postscript output shows that all the characters that are not-defined in Iso-latin-4 have reverted to their values in the default encoding. On the font encoding configuration screen they still show as not-defined.
