换句话说，要广泛部署的HTML文档中应使用的代码范围是什么
推荐答案
是否通过&＃xNNNN; 字符引用或只是通过键入或复制 - 直接粘贴到页面中，它只是一个字体的问题。如果用户有字体的字形，他们的网页浏览器知道，它会工作。如果他们没有，它将是一个小盒子。
Whether you enter them via &#xNNNN; character reference or just by typing or copy-pasting them directly into the page, it's purely a question of fonts. If the user has a glyph for the character in the fonts their web browser knows about, it'll work. If they don't, it'll be a little box.
fileformat.info有字体可用性细节，可以帮助猜测如何广泛的字形支持。例如。点击U + 25B6的此页面上的字体链接。对我来说，这在大多数平台上呈现，但不是在一个vanilla XP安装与IE6（IE7选择从Lucida Sans Unicode IE6 FSR不打扰看）。
fileformat.info have font-availability details that can be of help for guessing how widespread glyph support is. eg. hit the Fonts link on this page for U+25B6. For me, this renders on most platforms but not on a vanilla XP install with IE6 (IE7 picks it up from Lucida Sans Unicode which IE6 FSR doesn't bother look at).
◄ ► U+25C4, U+25BA Left/Right-Pointing Pointer glyphs seem to be more widely available than
◀▶U + 25C0，U + 25B6左/右三角形字形
◀ ▶ U+25C0, U+25B6 Left/Right-Pointing Triangle glyphs
所以我会使用它们。特别是他们在XP + IE6中使用默认字体渲染，因为它们存在于Arial中。这使他们更像三角形比指针是应该的。 （叹息）OTOH它的上/下三角形是好的。
so I'd use those instead. In particlar they render in XP+IE6 with default fonts because they are present in Arial. Which renders them more like Triangle than Pointer is supposed to be. (sigh) OTOH its up/down Triangles are fine.

还有‣，U + 2023三角项目，这是一个广泛存在的印刷版本的块。不幸的是，它不是在Arial或其他字体IE6上的默认XP将使用。也不是▸U + 25B8黑色右指小三角形。
There's also ‣, U+2023 Triangular Bullet, which is in a block of widely-available typographical-niceties. Unfortunately, again, it's not in Arial or other fonts IE6 on a default XP will use. Neither is ▸ U+25B8 Black Right-Pointing Small Triangle.
