charset and DateTime

[joerg128]

Hello,
I have the following problem:
first I use LANG=de_DE.UTF-8

if I ask for DateTimeOriginal I get
exiftool -d %Y-%m-%b FILE

Code Select Expand

2019-03-M?r

but for renaming the file I get
exiftool -d %Y-%m-%b '-filename<DateTimeOriginal' FILE

Code Select Expand

2019-03-Mär[|code]

Why this two different results?
What can I do?
Regards
Jörg

Hi Jörg,

Here is what I get in sh on Mac:

Dear Phil,
thank you for your fast response.
It seems that I have differences in the libraries. I installed exiftool via the DMG from your website.
Here are the output of exiftool -ver -v

Hi Jörg,

I suggest you install POSIX:strptime if possible.  My guess is that Time::Piece isn't handling locales properly.  ExifTool will use the POSIX library if it exists.

Hey Phil,

sorry, unfortunately no success
I installed POSIX::strptime and Unicode::LineBreak

It seem, that renaming and output of parameters are using different libraries.
