    skos:definition "Keyword marked with the # sign in social media posts and messages, used to group posts on one topic. It may contain letters of any script, digits and underscores, but no spaces or punctuation. X (Twitter) and Mastodon do not link a tag made only of digits, so the regexp requires at least one letter. Wikidata property P2572 stores hashtags without the # sign; the regexp requires it, because without it a hashtag is an ordinary word. Python matches letters of all scripts; the browser regexp engine matches only Latin letters, and neither matches combining vowel signs of Indic scripts."@en ;
