MediaWiki:Titleblacklist-custom-fullwidth
The page title that you have attempted to create contains fullwidth forms of Latin letters. Such characters should not normally be used in page titles. Please replace them with the normal letters (try putting your input method in half-width mode – on a Japanese keyboard, press the 半角/全角
key) and try again. If you got here by clicking on a red link in an article, you should go back and fix the link first.
If you have a good reason for creating a page with this title, or if you receive this message when attempting to edit an existing page, please let us know at Wikipedia:Administrators' noticeboard. Be sure to specify the exact title of the page you are trying to create or edit, as well as a brief explanation of what you were trying to do. Thank you.
