No I make no confusion: <wbr> is a formatting HTML element, SHY (or ­ in HTML syntax for the defined entity) is a character. Both play equivalent roles in HTML, except that ­ has a defined behavior to insert an hyphen at end of broken lines, where <wbr> would adopt a language-dependant behavior (not all languages use hyphens at end of lines to mark words that have been split by breaking lines). I really know that ­ and SHY are synonyms in this context but that <wbr> is a bit different and is not part of plain-text (notably it will be filtered out from $(element).innerText, but not ­ Note that some browsers are resolving the "innerText" property of HTML DOM elements by parsing the CSS properties, so this property does not really reflect only the plain-text elements of the document: Chrome for example does this to remove spans of texts that are hidden, either by display:none, or display:hidden, or color:transparent, and it transforms <br> elements into newlines, and detects the boundarty of block-elements (e.g. with "display:block" or "display:table-cell') to generate newline characters, or sometimes tabs. Chome also injects text added by CSS ":before" and ":after" selectors. The effect of all this is that a browser uses the HTML DOM to still infer some plain text to return for the innerText element property, and <wbr> may become a SHY format control (should it?)
