Appendix:Unsupported titles
Due to technical restrictions, some page names are not allowed on Wiktionary. Since Wiktionary uses the term being defined as the page name, there are thus some terms that cannot have their own entry. Some of these are collected here instead. (For more information on the technical restrictions, which are in the software that Wiktionary runs on, see the MediaWiki Handbook.)
When adding new entries with unsupported titles, update MediaWiki:Gadget-UnsupportedTitles.json and Module:unsupported titles/data (the backend for Template:unsupported).

Unsupported symbols
The following characters cannot be used at all:
# < > { } | �
Many of the above characters have special meanings in wiki syntax or HTML markup. The replacement character represents invalid UTF-8 sequences.
The non-printable control characters (0x00 to 0x1F inclusive and 0x7F, the "delete" character) are also unsupported.
Restrictions may apply to other characters:
- Titles cannot start with a colon.
- Relative path page titles (such as "." ".." or "/./") are invalid.
- Underscores are converted to spaces. Leading and trailing spaces/underscores are removed. Consecutive spaces and underscores between non-whitespace characters are reduced to one. Page titles consisting of only spaces or underscores are invalid as empty. Underscores can be displayed in page titles in place of spaces with the DISPLAYTITLE magic word, although in Wiktionary it is not used for consistency.
- Page titles cannot contain three or more consecutive tildes (
~). - A title may contain the character
%, unless it is followed by two hexadecimal digits. - A title may contain ampersands (
&) and semicolons (;), but titles cannot contain strings that could form an HTML character reference (e.g.>). This applies whether the string is a real reference or not (e.g.&foobar;is not defined in the HTML standard, but is still excluded from titles).

Unsupported length
No page title may be longer than 255 bytes (not characters) in UTF-8 encoding.
- Ancient Greek dish (full title would be 343 bytes)
- Thai name of Bangkok (full title would be 423 bytes)
Unsupported prefix
Titles can't have a prefix (letters before a colon) that is an interwiki (includes language codes and project codes) or a namespace prefix (which would place pages in a different namespace), including aliases. Prefixes are not case-sensitive.
