====Other uses for em dashes====
An [[#Indentation|indented]] em dash may be used when attributing the source of a passage, such as a [[#Block quotations|block quotation]] or poem. This dash should not be fully spaced: however, for reasons related to [[Wikipedia:Reuse|metadata]] and [[Wikipedia:Manual of Style/Accessibility|accessibility]], it is best to place a [[hair space]] between the dash and the name.{{efn|name=hairspace|The [[hair space]] should be done as {{mxt|{{tl|hair space}}}} because the actual Unicode character ({{hair space}}) is almost invisible, the meaning of the numerical HTML entity ({{!mxt|&amp;#8202;}}) is relatively obscure, and the named HTML entity "{{!mxt|&amp;hairsp;}}" is not standard and unsupported in some browsers.}} Most of Wikipedia's quotation templates provide this formatting automatically.

For example, {{mxt|{{tlp|in5}}—{{tl|hair space}}Charlotte Brontë}} will produce:

{{in5}}—{{hair space}}Charlotte Brontë
