How can I translate strange characters in Data to my Database?

I had purchased in the past from Retail shop simple access program that allows you to enter telephone , numbers, address , etc. from your contacts, my customers. The company that sell this program does not exist anymore so I cannot find anyone to help. When I open the tables from access I see strange characters in some columns . How can I translate these to  normal, so I can use to access or to export to excel?

ps. i attach example of column , (exported in excel)

you may have to use unicode for the character alone or in conjunction with xml that's encoded for that particular app...

It's possible that someone's been using cross-site scripting vulnerabilities to attack the site, or possibly injected it directly.

Offhand it looks like they equate to chinese characters which are often used to try and hide injections.
