Module:Sandbox/Luis150902/cleanup

File:Ambox warning blue construction.svg

This module is rated as pre-alpha. It is unfinished, and may or may not be in active development. It should not be used from article namespace pages. Modules remain pre-alpha until the original editor (or someone who takes one over if it is abandoned for some time) is satisfied with the basic structure.

UsageEdit

{{#invoke:Sandbox/Luis150902/cleanup|main|string}}, where string is the string to be escaped. This eases the editing of wiki markup containing bidirectional text. Inserting = (escaped form of =) is displayed as ;61#& between right-to-left characters.
