Template:!
From LGPedia
|
This is an auxiliary template allowing to encode "|"
within template parameters. It is unnecessary to get a
"|" in these cases, better use "|"
for this purpose. However the "|" delimiter for a
Wiki table has to be escaped by a template if it is used
in a parser function.
Note that there's no such problem with "!" (exclamation mark), it
only affects "|" (vertical bar) within tables.
For obvious reasons this is a high risk template.
