"You must provide it clean (interchange-valid) UTF-8, so any encoding issues must be sorted out before-hand."

In most cases you have to know the language in order to guess the encoding and convert to UTF-8 if necessary. Mutual recursion...

I'd say in most cases UTF-8 is already used. Of course this depends on the source of the text.

Mark Pilgrim reversed (or ripped out, can't remember) the encoding detection that Firefox uses. It has done a fairly good job for my web crawling:

In my experience chardet misclassifies very often iso-8859-1 as iso-8859-2. I saw the misclassification even in small spanish pages, which were using only the typical spanish characters.

I thought that the detection is easier with Unicode ordinal value map table

I am assuming it will recognize languages even when they are using the same character sets. No?

Nice! I wrote a .NET wrapper myself, never got around to a Python extension though. One question - did you experience any memory leak issues with the CLD? Said, .NET wrapper DLL seems to leak and I never really checked if it was the C++/CLI I added on top or the actual CLD native C++ code. I doubt the latter since (according to my basic understanding) nothing is created in the original code which needs to be cleaned up manually. Before I start debugging mixed-mode .NET applications I just wanted to be sure.
