How to remove garbage at the end of lines in a text document?

Question

Regular Expressions

At the end of a text document, at the end of each line, I have some kind of spaces that look like a space, but these are not spaces or tabs because I tried to remove them with standard functions in a notepad like Edit-> Remove spaces at the end of a line, Edit-> Spaces in tabulation, tabulation into a space, etc. this does not help anything ... Is there any way through a regular expression that will clean everything up to the last character?
