Backslash is removed from everything

MajorMinor can't be recorded with its real name because the backslash is removed. Forward slash works fine.

Backslash is commonly used as an escape character in programming languages, so I presume this is case of overeager sanitation of the title.

Apparently backslash is removed even from these articles as well. Not sure if it's because it was inside BBcode or in general.

Edit: Backslash is removed from everything, since it doesn't work even in these articles (testtest, test/test)

And skus with slashes in them are not accepted as valid.
