Jehan 94b10b9b29 Bug 101030 - Buffer overflow related to ISO2022JP detection in...
... en:ascii and ja:iso-2022-jp tests.
I don't know much about this part of the code at this point. Yet I can
clearly deduct that the length of the charLenTable is supposed to be the
classFactor of the SMModel. Therefore 2 classes were missing in
ISO2022JPCharLenTable, hence a buffer overflow happens when trying to
reach these. I am not sure of the values I should add there. For now,
let's set 0 to both, but adding also a comment so that I can review this
code later on, when I will get to read and understand this piece of code
in more depth.

uchardet

uchardet is an encoding detector library, which takes a sequence of bytes in an unknown character encoding without any additional information, and attempts to determine the encoding of the text. Returned encoding names are iconv-compatible.

uchardet started as a C language binding of the original C++ implementation of the universal charset detection library by Mozilla. It can now detect more charsets, and more reliably than the original implementation.

The original code of universalchardet is available at http://lxr.mozilla.org/seamonkey/source/extensions/universalchardet/

Techniques used by universalchardet are described at http://www.mozilla.org/projects/intl/UniversalCharsetDetection.html
