It's not, Unicode is just a number to glyph mapping, and UTF-8, what you
probably mean, uses the eighth bit too, which cannot be said of ASCII -
ASCII is a 7 bit character set.

Unfortunately unless $record is all ASCII $test and $record will always
differ, because every byte stream is valid latin1 and can thus be
converted to UTF-8.
What you can do is to manually replace à à à  and all other non-ASCII
byte values with their UTF-8 equivalent and then go through the data
manually to check it for correctness.
Another hint you can get at in your program is to try to check if your
input is valid UTF-8 and only convert from latin1 if it is not. You can
probably check for valid UTF-8 by seeing if the conversion from UTF-8 to
UTF-8 succeeds.
