 This could be a case of garbage in = garbage out but I noticed that
 calling

 `translate( null, "domain" )` or `translate( "", "domain" )` produces an
 unexpected result when

 - the text domain for "domain" is loaded
 - and it contains a translation for "0".

 === Expected output ===
 null or null string

 === Actual output ===
 translation of the `"0"` string

 === Workaround ===
 Don't call translate() this way.

 === Question ===
 Could/should there be a unit test to confirm what should happen?
