PROBLEM WITH CHARACTERS

[#1]

Hi! Recently my PDF reader has had the "weird" characters. I have already updated Adobe and Windows to the latest available version, however, the problem persists. My Adobe's language default is set to Portuguese (Brazil). Documents that were always displayed normally, today have this problem so, I suppose it is not a lack of sources. Is it a problem with any version of the software? Is Adobe aware of this already? Do you have a momentary solution? Thank you very much in advance!

What's the exact version number of the application (You can find it out by going to Help - About Adobe Acrobat)? What's your OS version? Can you share a sample file with us that has this issue?
