Usually reading something like electricity bills online will display a web page with the details.
Is your Electricity Utility offering a download of your bill? If so, then it is likely to be in PDF format, and for that you will need a dedicated PDF Reader.
Adobe is the PDF developer, but their Adobe Acrobat PDF Reader can be a bit buggy. There are free alternatives, like Foxit Reader from http://www.foxitsoftware.com/pdf/reader/
Check which format the utility web site is offering this bill. If it is a download, do not "Download and run", but instead "Download and save", then save the file to your Desktop. If it is in PDF format, download and install Foxit reader, and use that to read the file.
When I want to read, for example , an electric bill on line, Word appears but the code is in Western European (Windows). It is totally unreadable and no matter what code I choose it remains unreadable. Can anyone please help, I need to be able to read my Documents.
