Heavy vs normal and spelling mistakes #25
Description
We're using tinyld to detect the language on some external content, which generally works great. I'm looking to move to the heavy version to fix a detection error, but I noticed that one of our test cases started to fail. It's based on the title of https://www.scienceopen.com/hosted-document?doi=10.14293/S2199-1006.1.SOR-.PPL3VEC.v2, which contains a couple of spelling mistakes.
The normal version correctly identifies it as Spanish:
tinyld --verbose "Notas para una aproximacin al punk espaol y sus contextos"

I need to learn more about the library internals, and spelling mistakes will always be a problem, but is there anything worth tweaking?
