How escape pipe charachter in MediaWiki parser function?

问题

How do I escape a pipe character using a MediaWiki parser function?

Replacing a backslash by a hyphen can be like this:

{{#vardefine:varName|test\test\test}}
{{#vardefine:varName2|{{#replace:{{#var:varName}}|\|-}}}}
{{#var:varName2}}

But replacing a pipe character ...?

回答1:

Use the built-in magic word {{!}} instead of litteral pipes.
