I am trying to post a quote as part of a question. The quote includes a portion of a sentence that is underlined and I can't see how to do that here. It isn't under Styling/Headers, and I've tried [u]underline[/u] and that also didn't work. What is the formatting for underline here? Thanks
Underlining is not supported in user posts.
One reason is that underlining in web pages is customarily used for links, and your text would [probably] not be a link. The other reason is that the designers don't like it: underlining isn't used in any Stack Exchange site, as far as I am aware — even for links.
Normally, it's acceptable to find some other form of emphasis. If underlining is only used to draw attention to a few words, then bold or italic will do just as well. However, there are conventions there too: italic is used for mentions of a word, and bold is preferred for emphasis.
Dan Bron has already commented about using the
> character as a prefix for a quoted paragraph. Within the quote, you can use any of the available forms of emphasis. But underlining is not one of them.
Note: many user agents/operating systems can have problems with special Unicode characters such as those which include or combine to make an underline, or provide small capitals or whatever. Please don't use them. For example, although
̲a appears fine in a monospaced font, it probably doesn't look right in Georgia as used for the body text in this site: ̲a. It certainly doesn't look right in my browser — this is what I see:
