This is an auxiliary template allowing to encode "
|" within template parameters. It is necessary if the character is used in wiki table syntax. In other cases it is better to use "
This template cannot be used for putting the character as text in a wiki table; in that case, again, "

This is a high risk template, and it cannot be substituted.
