Typography: <u> should not be used to underline text in HTML5?

[florianlacreuse]

According the the HTML5 specs and as explained here, <u> has been previously deprecated and reintroduced with a new meaning.

This element used to be called the "Underline" element in older versions of HTML, and is still sometimes misused in this way. To underline text, you should instead apply a style that includes the CSS text-decoration property set to underline.

However, the BS docs suggests to use <u> element to underline text as it's used to be in the past (as I understand it): https://getbootstrap.com/docs/4.3/content/typography/#inline-text-elements

One more thing, from this ressource from w3 about <b>, <i>, etc.:

The following HTML elements specify font information. Although they are not all deprecated, their use is discouraged in favor of style sheets.

May be BS should at least provide an utility class to underline text? We can already use .font-weight-bold instead of <b> and .font-italic instead of <i>.

Yeah, I think this would be a good addition. Personally I almost never have to use u, b or i
