UTF-8 encoding while replacing string [SOLVED]

#1 Post by AlphaInc. » 05 Aug 2021 12:10

Hello everybody,

I recently set a mediaInfo script that outputs information about different media files inside a specific folder.
Now after every output I need to change some strings in the created output. For that I use the following command:

Code: Select all

powershell -Command "(gc myFile.txt) -replace 'foo', 'bar' | Out-File -encoding ASCII myFile.txt"
The problem I have is that there is an Umlaut which gets replaced (ö turns into ??). I also tried to replace ASCII encoding with utf8 with no success. Is there anyway to get my Umlaut into my encoded text-file OR use another string-replacement-string ?

The important question is, what's the encoding of the input? If you know it, you have to specify it along with gc.
FWIW Obviously ASCII makes things worse because only 7-bit ASCII characters are supported in this case.

I don’t know, I created the txt file by using Mediainfo with a template and then output it (Mediainfo -Inform=file://template.txt Video.mkv >> Output.txt) to a text file.

I don't know anything about mediaInfo-
Try to run the tool I uploaded in Jean-François' thread. Maybe it's able to tell you the encoding.

If you don't succeed, put the text file in a zip archive and upload it here. I'll probably find it out for you in no time.

I'll try it, thank you.
But (for all who may run into something similar) found a workaround for that. I replaced the powershell command with a python script which replaces the string without having to deal with the encoding of the file. Maybe not ideal but it's good enough for my use case.

python script
If Python works out of the box then it's a strong indication that the text is UTF-8-encoded.
