The 'file is text' check searches for #0..#8,#11,#12,#14..#31.
There are no special Unicode characters in #0..#31.

I checked libsvn-dev and you are right - it contains the special char
#12 - Form Feed.
I checked several viewers and editors and none like them. But they
don't warn neither. Apparently they ignore this special printer
character.
I changed FileIstText to allow 'Form Feed'.
