After creating a simple config file following this code from 2013:

Yes, this is how to define a tag with a name that is different from the ID:
%Image::ExifTool::UserDefined = (
'Image::ExifTool::PDF::Info' => {
'ID with spaces' => {
Name => 'SomeTagName',
Description => 'Some description',
},
},
);

After running:
exiftool -config config.txt -PDF:SomeTagName='test' file.pdf
When I check the results with:
exiftool -a -G1 file.pdf
I get this:
[ExifTool] ExifTool Version Number : 11.16
[System] File Name : file.pdf
[System] Directory : .

[PDF] Page Count : 50
[PDF] ID : withInstead of something like:
[PDF] ID with spaces : test
And when I check it in Adobe Acrobat, there're no user defined tags nor values.
I don't know if the code in no longer usable or I'm making a mistake. I hope somebody can help me.
Thank you very much in advance.
It it legal to have a space in a PDF tag ID? I don't recall ever having seen this.
- Phil
In Adobe Acrobat you can insert tags with spaces in their IDs. When you look at them with exiftool you get a little garbage:
[XMP-pdfx] Fecha 0020de 0020edicin : 2001
Where U+0020 is the Unicode for space. I've been trying to replicate this with exiftool without success.
That is not a PDF tag, it is an XMP tag. What does the source XMP look like for this tag?:
exiftool -xmp -b FILE
- Phil
Thank you very much for your reply.
The whole -xmp -b output is:

That is truly odd. The actual tag ID is "Fechaↂ0020deↂ0020edición". Wild. Or with the special characters escaped "Fecha\xe2\x86\x820020de\xe2\x86\x820020edici\xc3\xb3n". So the config file would look something like this:
%Image::ExifTool::UserDefined = (
'Image::ExifTool::XMP::pdfx' => {
"Fecha\xe2\x86\x820020de\xe2\x86\x820020edici\xc3\xb3n" => {
Name => 'FechaDeEdicion',
},
},
);
1; #end
...but I wouldn't recomment using tags with such crazy ID's.
ExifTool tag names can not contain special characters, so without the config file to change the name, it would look like this: "Fecha0020de0020edicin".

I've tried it, and Adobe Acrobat doesn't show any tags, but I've found another "space" (U+00A0 - \xc2\xa0) character and using it:
%Image::ExifTool::UserDefined = (
'Image::ExifTool::XMP::pdfx' => {
"Fecha\xc2\xa0de\xc2\xa0edici\xc3\xb3n" => {
Name => 'FechaDeEdicion',
},
},
);
1; #end
Acrobat shows and exports it as a regular space (Fecha de edición).
Nevertheless, I'll do my best to persuade my team to use standardized tags.
Thank you very, very much for your help and your amazing work.
