7998: ANSI targets are deprecated

Question

How can I resolve "7998: ANSI targets are deprecated"?

When I add Unicode True

I get error,

Error: Can't change target charset after data already got compressed or header already changed!
Error in script -- on line 58
-- aborting creation process

Unicode True needs to be set very early in your .NSI file, before any !include statements and before any File commands.
