Continuation depends on backslash parity
An odd run before a line ending continues the logical line. The terminator and leading whitespace on the next natural line do not become value characters.

What this tool does
Bounded, explicit, and local
Properties files have natural and logical lines, odd-backslash continuation, flexible key separators, and their own escape behavior. Validation reports those rules without loading a resource bundle or another file.
Encoding depends on the loading API
This text tool validates characters already present in the browser. Java's Reader, InputStream, and PropertyResourceBundle paths have different encoding contracts that remain the caller's responsibility.
