perl foo.pl where foo.pl has bom will work on every platform

./foo.pl if .pl has been assoc-iated with perl will run on win32, and if foo.pl has bom it will be BOM-ed

./foo.pl won't work on unix if foo.pl has bom because shebang won't be detected and perl won't be called, the bom interferes with shebang

editors like notepad/scite... like the BOM ... I like the BOM even though I type in ASCII ... because I copy/paste stuff from the internet, and utf is the only way not to lose info ... most editors don't make files utf by default leading to corruption without BOM
