Hi All,
I have a text file which is thousands of lines long but for some reason I'm getting random question marks showing up on some lines which are not wanted.

Example lines in text file.

At the moment I just open the text file up in notepad and do a find and replace but I want to automate this in Powershell.
So I need a script which simply deletes all the question marks but leaves the rest of the line intact so from the above example to the below.

Try with a single file copied in a test folder:

Dir |
Rename-Item -NewName { $_.Name -replace "?","" }

Open in new window

I would try to investigate the source of the question marks.  For example:
- is it something that can be fixed by whatever generates the file?
- are they real question marks (certain programs will show a symbol that kind of looks like a question mark when there is a character that can not be displayed)?

To just remove the question marks though you can use the following.
(Get-Content yourfile.txt) -replace "\?" | Set-Content yourfile.txt

Open in new window

I will get blood out of a stone before I get a developer to look at the program that makes it.  So its up to me to fix it.

The above solution worked thanks.
