Iam writing my bachelor thesis at the moment. The problem for me is now the spellchecker (I use Open Office but this is a general problem) won't recognize .NET as a valid word. A also cannot add it to a user specific dictionary because of the leading dot. Also the grammar checker has a mayor problem with the dot.
I consider this a general problem with spell-checkers and grammar-checking software. If I recall correctly for a similar reason they invented a lowercase and a uppercase version of ß (German letter 'S-Z', Html entity: ß) but which are both looking the same.
To make it short, is there a unicode symbol which looks like a dot but is classified as a letter symbol?
