Template Documentation(for the above template, sometimes hidden or invisible) (view - edit - history)
This is an auxiliary template allowing one to encode "|" within template and parser function parameters, which they otherwise identify it as a separation character of parameters. To get the symbol in final output this template is unnecessary, better use "|" which is rendered the same. Use this template in parameter values of templates and parser functions of which the result is used in table syntax, since this requires the "real" pipe character.
This template cannot be used for putting the character "|" as text in a wiki table; in that case use "|".
