 | This is a documentation subpage for Template:Popdf. It may contain usage information, categories and other content that is not part of the original template page. |
This template {{popdf}} adds U+202C POP DIRECTIONAL FORMATTING (or by character acronym PDF). It is an invisible formatting character, which only affects directionality of text. Its general Unicode acronym "PDF" cannot be used for this template, since it already has a different meaning.
Usage
edit{{popdf}} adds an invisible character that marks the end of a text to be in forced directionality. That forced directionality can be started with: {{lro}}, {{rlo}}, RLE, LRE "opening" marks.
Note that it is not needed when using the RLM or LRM character, since these marks are standing alone, and are not "opening" marks.
