Agreed. In fact, I was also fixing bug #75065, maybe duplicate.
I have a fix for UTF8Encoding, but it uncovered another mcs bug
which does not handle files with BOM with specific encoding.
To summarize the situation:

	- Currently driver.cs does not process source files with
	  default encoding.
	- UTF8Encoding.cs does not handle U+FEFF correctly.
	- When we fix UTF8Encoding.cs to handle U+FEFF, it starts
	  to reject some source files which has BOM.
	  (CS8025:Parsing error)
	- Even if we fix driver.cs to let StreamReader consider BOM
	  (currently we disable it), there are still some files

Am digging into this bug in depth. Hopefully I'll post a set of
fixes later.
