This is an auxiliary [[Wikipedia:Help:Template|template]] that allows one to encode "<code>||</code>" (two pipes or [[Wikipedia:vertical bar|vertical bar]]s) within template parameters. If it is '''unnecessary''' to get a "<code>||</code>", it is better to use "<code>&#124;&#124;</code>". However the "<code>||</code>" delimiter for a [[Wikipedia:Manual of Style/Tables|Wiki table]] has to be [[:Category:Character-substitution templates|escaped by a template]] if it is used within a template.

== Notes ==

There is usually no such problem with "<code>!!</code>" (exclamation marks). This problem only affects "<code>||</code>" (vertical bars) in conjunction with the [[mediawikiwiki:Help:Parameter default]] mechanism within tables. However, in table rows starting with "<code>!</code>" there can be problems with "<code>!!</code>" being interpreted as a cell separator. Try replacing it with "<code>&#33;&#33;</code>".

This template cannot be [[Wikipedia:Substitution|substituted]].

== Parameters ==

<TemplateData>{
"description": "Escapes double pipe characters within template parameters",
"params": {}
}</TemplateData>
