Language metadata tag causes embedded python error

mrprobert · 12-11-2022, 06:31 AM

Hi,

An epub I have has the language metadata tag set to: <dc:language>eng</dc:language>. Invoking the metadata editor changes the tag to: <dc:language></dc:language>, which I assume is an incorrect. Invoking the editor a second time throws an embedded python error.

To reproduce this behavior:

Create a simple epub and change the metadata language tag in the opf to: <dc:language>eng</dc:language>
Open the metadata editor and then click OK.
Opening the metadata editor a second time throws an embedded python error.

I can get around this by editing the opf and deleting the language tag but I wonder if there is a better way to deal with this situation.

Yes, "eng" is not a valid dc:language value. And the python error when using an empty language tag has already been fixed in master. Use the metadata editor and select a the dc language tag and select a valid language.

Also see my post from a few months ago:

2022: "Issue with SpellCheck?"

where I described the "eng" language mistake in more detail.

In EPUB metadata (and HTML lang):

✗ eng
✓ en = English
✓ en-US = English (United States)
✓ en-GB = English (British)
✗ en-UK

Hmmmm... this seems like a common enough error... (We've had many posts like this over the years.)

Should there maybe be some auto-substitution of eng -> en instead of throwing it away / blanking it out?

No. We're not going down the rabbit hole of trying to auto-fix incorrect language codes.
