square boxes displaying in .wmf

I have a program which uses technical drawings in a .wmf format.  Until recently they all displayed correctly now any which include foreign language characters in the display text have replaced accented letters with square boxes.

Can anyone tell me what the solution to this problem is?  Also, what is causing it?  I did not think that an image file could be changed or is a .wmf not an image file?

.wmf are windows metafiles see what wikipedia tells about them

The problem you state seems like a problem with character encoding. Vector graphics can contain text, and this text should be encoded on a determinate character encoding. I guess if that files come to you from an external source, probably where they are being created the so is in a language that understands the specific accented characters but when you try to load it on a different system with a different characters set they aren't recognized if the file doesn't state an specific character encoding to use.

Thank you for the explaination about windows metafiles.

The metafiles in question have been sitting on our server for a number of years and have always appeared correctly up until now.

I think the cause of the files now having some foregin language characters appear as squares must lie on our server.  I have additional language support and nothing appears to have changed.

Would you have any idea's what files or drivers govern the appearance of the text part of window metafiles and where I might start to look for the problem.

Thank you.

Actually I don't know well the structure of a .wmf, however, if your server was able to read those characters before and now it show them as unrecognizable characters something must have changed on it's language configuration.

With the information supplied I unistalled and reinstalled the various languages in the Region Settings and Languages Advanced option and after rebooting the server the problem of the missing characters went away.
