WikiLinks can be entered in any case you like, the page they link to is
always lowercased.
-Note that if the file linked to by a WikiLink looks like an image, it will be displayed inline on the page.
+While a WikiLink is limited to alphanumerics and only a few special
+charaters, it is possible to create page names containing other characters:
+
+* To display a page name with a space in it, use "\_" in the WikiLink, for
+ example, "\[[Multi\_Word\_Page\_Name]]".
+* For any other special character, you can use "\_\__nnnn_\_\_" where
+ _nnnn_ is the unicode character number. For example,
+ "\[[This\_page\_name\_is\_\_44\_\_\_uselessly\_\_44\_\_\_a\_complete\_sentence\_\_46\_\_]]"
+ Limiting use of this to when you really need it is a good idea.
