Well, i thought i did.

i really don't need anyone to reproduce it. i'm really asking if anyone have
had the same issue with a relatively recent source code, i'm myself using it
from C++ with the wrapper API.
Basically: is the behavior of the "tessedit_char_whitelist" the same as before?
Or did it change in some way? In previous versions it was not only a hint to
the classifier, but would also completely disallow it to follow learnt paths
other than the ones in the whitelist. Now it seems to be different, because
(And again, whatever the image is) the output contains characters not in this
whitelist.
The basic idea of a whitelist is a safer blacklist… Blacklist tends to be a way
to exclude few possibilities, while whitelist tends to include only a given
amount. i would like to know if this behavior is still the same, that's it.

Whatever the image is, the output is in contradiction with a basic rule
(Whitelist) which used to work when i first started to use tesseract years ago
with older versions.
As a code snipet, the only useful piece of code i can think of copy pasting
would be this line:
>>> _tessApi->setVariable("tessedit_char_whitelist", "><0123456789");
But the result i get contains other characters, not allowed by the whitelist:
>>> 3000657806S<00S60':0<3000657B0<
Again: i'm using a fresh svn HEAD version of tesseract via the C++ wrapping API.
Would it be possible for anyone here to give me a snippet of a working
whitelist, as it was conceptually made in the previous versions?
Thanks a lot,
Pierre.
