Please describe the problem:
Writing letter which has no corresponding glyph in embeded fonts results in warning on stderr and charater doesn't display after commiting the change or in printed PS output.

Steps to reproduce:
1. Open PDF with input line from element and focus input line
2. Input character which is not in embeded font
3. Commit the change (and print the file).


Actual results:
During editing system font is used and charater is displayed properly. However after that the input line text is type set by PDF font. If the font has no corresponding glyph, the letter will be omitted and not shown. You get message like "warning: layoutText: cannot convert U+0159".

Expected results:
Evince should be able to emebed new font from system into the PDF and use it instead the original one for the problematic letter or input line or all form elements.

Does this happen every time?
Yes.

Other information:
Acrobat Reader does it (except saving the PDF file). Such a problematic PDF file can be produced with OpenOffice.org because it emebeds only minimal usable subset of the font.
