When the user enters non-Latin1 text into the properties source editor and than saves the file, all non-Latin1 characters are saved as '?' (question mark character). The user should be warned and offered translation of the file so that these characters are written in form of \uxxxx sequences.

Accepted.
Now that issue #32392 ("Edit Text Rather than Escape Sequences") has been fixed, characters not encodable using the ISO-8859-1 (Latin 1) encoding are saved in form of \uxxxx sequences and decoded when the file is loaded to the editor - there is no loss of information. See also issue #97861 ("Update properties data object to use FileEncodingQuery").
