Henrique de Moraes Holschuh:
Also, a text file MAY contain NULs (the character), it is just
considered bad practice (nowadays?). Don't assume you won't see any.
For example, received e-mail is *more* likely to have NULs in it than
normal text due to the quality of some mail agents out there.
I suspect not as likely as anything that was in the process of being
appended to on a not-fully-journalling filesystem when a dirty shutdown
happens. (-:

Or anything that "rotates" output files by truncating them and pulls the
rug out from underneath an old-style simplistic indefinitely-running
text output writer.
