How can I pass a default value for the case of a non-existent or empty-string translation?

Example

In every non-English language, I have a translation for the warningMessage variable. In the example, I copied the German file. The text in English is: Attention! The original language of the page is English. You are currently browsing a page translated into German by the community. If you encounter any errors, please let us know!

Naturally, I don't want to display it in English, so in the English file, I declare an empty string (to avoid discrepancies between the two files).

de.json

{
  "warningMessage": "Achtung! Die Originalsprache der Seite ist Englisch. Sie durchsuchen gerade eine von der Gemeinschaft ins Deutsche übersetzte Seite. Wenn Sie Fehler bemerken, lassen Sie es uns bitte wissen!",
}

en.json

{
  "warningMessage": "",
}

Problem

However, when I invoke the trans('warningMessage') function in English, it returns warningMessage instead of an empty string. How can I provide the function with a default value for the case of an empty string or undeclared variable?

Solution?

I temporarily added a space to the text. However, in this case, the length of the text is not 0 but 1, which is illogical for an empty string. Is there another solution? I would like to instruct the trans function to output nothing in the case of a 0-length string value in this situation.

en.json

{
  "warningMessage": " ", // space
}

Request

I think it would be perfectly fine to leave the trans function as it is and create another function, perhaps named nullableTrans or any other name, whose purpose is to avoid outputting the key as a result when the key does not exist or its value is of zero length.

While displaying the key is very useful, there are a few cases across multiple projects where I want to avoid it without having to modify the trans function everywhere afterward.

de.json

{
  "warningMessage": "Achtung! ...",
}

trans("warningMessage") // result: "Achtung! ..."
nullableTrans("warningMessage") // result: "Achtung! ..."

en.json

{
  "warningMessage": "",
}

trans("warningMessage") // result: "warningMessage"
nullableTrans("warningMessage") // result: ""

cz.json

{
  "anotherKey": "...",
  // warningMessage not declared
}

trans("warningMessage") // result: "warningMessage"
nullableTrans("warningMessage") // result: ""

Hey @rozsazoltan will take a look on that shortly, thanks for the report.

Released the fix on v2.7.2.

Thanks for that.
