Why do I receive an error with the DATENUM function when exporting PNG-files from MATLAB 7.0 (R14)?

If I attempt to export a PNG-file with the following code:

figure;

plot( 1:1:10, 1:1:10, 'ro--' ); grid on; hold on;

print( '-dpng', 'Testplot.png' );

I receive the following error:

 ??? Error using ==> print

 Error using ==> print

 DATENUM failed.

 Failed to parse date string.

 Error using ==> datevec

 Failed to lookup month of year.

This bug has been fixed in Release 14 Service Pack 2 (R14SP2). For previous releases, read below for any possible workarounds:

There is a bug in MATLAB 7.0 (R14) in the way that the DATENUM function handles extended ASCII characters, such as those appearing in certain month names in languages other than English.

To work around this issue, try exporting to a different file format.
