Invalid encoding

[Melanie25205602287x]

When I edit an existing PDG I get this message error:

"Font Arial Bold 1252 contains an invalid encoding. Some characters may not display"

My PDF become unreadable...  

How can I fix this?

Have you created the file?

No

the source is our accounting software.  I wanted to add a backup to it, but it wont recognize de caractere.

Would it be to go directly in our accounting sotware and change the caractere to something else?

Looks like a issue of this software.
