Language alternate field with value 0 not respected

[charger]

I have the two integer fields called price and price_de. When I request the value of price with language de, it only provides the correct value if price_de is any other than empty or greater than 0. While I would expect an empty field to fall back to the value of the default language, having a value 0 should actually return 0. I set the option Blank and 0 have different meanings in both fields. I’m currently running PW 3.0.165.

Anyone else experiencing this?

Can someone reproduce this behavior to check if this is a bug?

So the culprit is here: https://github.com/processwire/processwire/blob/master/wire/modules/LanguageSupport/LanguageSupportFields.module#L159

Using empty() to check for a value in the field will return true if that value is 0. I changed it to !isset() and now it is working as expected.
