[Scons-users] ClassicCPP scanner fails with UTF-8 BOM on non-UTF8 file

[Bill Deegan]

Which version of SCons, Python, and what OS are you using?

You could write a scanner which is more than just a REGEX and reject
certain files.
I can't really understand your map of the source flows. can you write it
out with words?
