I understood better the problem, in short the first time I post-to-blog works fine. If I do it again it will substitute the already quoted characters with other interpreted characters.
This is likely a bug in WordPress or one of the plug-ins you have installed for it.
Normally WordPress shouldn’t touch stuff inside <pre> but there has been *a lot* of bugs related to this and sometimes fixed bugs reappear — I actually run a plug-in which tries to disable all the transformations that WordPress may do. That said, if your content is posted as Markdown, these transformations should happen at display-time.
