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, "
|" can be used.
Note that no special template is needed for "
!" (exclamation mark).
This is a high risk template, and it cannot be substituted.
