Hyphen is turned into HTML hexadecimal code in “view source” mode
-
Noticed a strange thing. If you view a page in w3 validator or in a “view souce” mode of a browser (Chrome/Edge) the hyphens would turn into hexadecimal symbol –
Checked other websites built on different CMS, the hyphen is present.
WP + Seo Framework – view-source:https://pokatushkin.ru/services/prokat-samokatov/
Drupal – view-source:https://www.tran-express.ru/
1c Bitrix – view-source:https://lenwood.ru/All 3 pages have the word with a hyphen “Санкт-Петербург”, though only WP with the SF plugin feature – instead of just ‘-‘
Can I do something about it? Should I?

Hello!
This is intentional behavior and there’s nothing you need to do. Search engines and all popular social platforms can decode special HTML characters from titles and descriptions; after all, HTML elements may contain HTML entities.
Here’s why we do this: TSF parses titles and descriptions through WordPress’s texturization (wptexturize()), which converts hyphens (charcode 45) to en-dashes (charcode 8211). Funnily, its documentation page fails to show a hyphen correctly but shows an en-dash instead.
In any case, because the hyphen is often used as a title separator, we want to maintain the unaltered hyphen. So, to prevent
wptexturize()from converting the hyphen to an en-dash, we convert the hyphen to an HTML formatted hyphen:-.Still, some users wish to show an em-dash (using two hyphens:
--=—), or endash as intended. So, we determine when we insert the-using advanced regex.I hope this makes sense. Cheers!
