HTML entity

@Redrose64: Greetings! I was just curious about this revert. I don't see any difference in rendering of ▲ vs. ▲. We use the raw Unicode character for ■, so I'm wondering what the rationale for using an HTML entity for the triangle is? This edit was part of a general effort to make wikitext as WYSIWYG as possible without changing characters that are too easily confused. -- Beland (talk) 04:36, 26 May 2020 (UTC)[reply]

The square I hadn't spotted, it should be ■ also. Not everybody has the appropriate fonts installed, and for those that don't, they'll see an unintelligible little box. With the entity, examining the page source shows the Unicode value, so that it may be looked up. Scripts exist to aid the entry of the entity. User talk:Redrose64/unclassified 24#"please don't mess with my sig" is related. There is a guideline on the matter, somewhere. --Redrose64 🌹 (talk) 08:51, 26 May 2020 (UTC)[reply]

Hmm, interesting perspective. The vast majority of readers don't know what an HTML entity is, though, much less how to look up a decimal or hex number to find the character. If a significant number of users don't have an installed font to represent a triangle, the only way most of them would know it's supposed to be a triangle there (other than the words saying so) is if we replaced the Unicode character with an image, or used a web font so the required fonts don't have to be installed locally. In this case, the symbols have been in Unicode for over 20 years, so I'd be surprised if any modern browser is having trouble displaying them. (If there are, it would be interesting to know.) The only approved guideline I know of is MOS:MARKUP, which says to avoid HTML markup generally, but to use HTML entities if characters are easily confused, like Latin "A" vs. Greek "Α". I'm not aware of another Unicode character these would be confused with, and in this case it probably wouldn't matter anyway. -- Beland (talk) 17:08, 26 May 2020 (UTC)[reply]
