Hi,

Unfortunately not. A line like

Line_without_a_equal_sign_is_also_invalid


result in an entry like this:

Key = Line_without_a_equal_sign_is_also_invalid
Value = Line_without_a_equal_sign_is_also_invalid

We simply do not split without an equal sign, so key and value are
equal. And maybe are also valid keys and values.
