Cheat Engine

[nik0la.vr]

I will just bring this up in case that someone else encounters this issue.

I was trying out Cheat Engine while using Calculator to do some calculations. CE kept complaining about invalid addresses from time to time and I've found out that calculator is to blame. Basically result from the calculator is enclosed with some invisible characters and CE doesn't like them.

They will try to fix this.

Just type out the address. Or you could try to remove those characters: when you paste the address, place cursor at the beginning, hold Shift and press right arrow (that should select invisible character), then press delete. Do the similar thing for the other end.

If you're making some notes in a text file and those characters are also present there, open up Search & Replace, turn on RegEx (regular expressions), search for [^\x00-\x7F]+ and replace it with blank. That should remove all unicode characters from the document.
