Is there an upside down caret character?
提问by Joel Coehoorn
I have to maintain a large number of classic ASP pages, many of which have tabular data with no sort capabilities at all. Whatever order the original developer used in the database query is what you're stuck with.
我必须维护大量经典的 ASP 页面，其中许多页面都有表格数据，根本没有排序功能。无论原始开发人员在数据库查询中使用的顺序是什么，您都会遇到麻烦。
I want to to tack on some basic sorting to a bunch of these pages, and I'm doing it all client side with javascript. I already have the basic script done to sort a given table on a given column in a given direction, and it works well as long as the table is limited by certain conventions we follow here.
我想对一堆这些页面进行一些基本的排序，并且我正在使用 javascript 进行所有客户端排序。我已经完成了在给定方向上对给定列上的给定表格进行排序的基本脚本，只要表格受到我们在此处遵循的某些约定的限制，它就可以很好地工作。
What I want to do for the UI is just indicate sort direction with the caret character ( ^ ) and ... what? Is there a special character that is the direct opposite of a caret? The letter vwon't quite cut it. Alternatively, is there another character pairing I can use?
我想要为 UI 做的只是用插入字符 ( ^ ) 指示排序方向，然后……什么？是否有与插入符号直接相反的特殊字符？这封信v不会完全削减它。或者，我可以使用其他字符配对吗？

There's always a lowercase "v". But seriously, aside from Unicode, all I can find would be &darr, which looks like ↓.
总是有一个小写的“v”。但说真的，除了 Unicode，我能找到的只有&darr，它看起来像 ↓。

An upside-down circumflex is called a caron, or a há?ek.
颠倒的抑扬符称为caron或 há?ek。
It has an HTML entity in the TADS Latin-2 extension to HTML: ˇand looks like this: ˇ which unfortunately doesn't display in the same size/proportion as the ^ caret.
它在 HTML: 的 TADS Latin-2 扩展中有一个 HTML 实体，ˇ看起来像这样：ˇ 不幸的是，它的显示大小/比例与 ^ 插入符号不同。
Or you can use the unicode U+30C.
或者您可以使用 unicode U+30C。

A powerful option – and one which also boosts creativity – is designing your own characters using box drawing characters.
一个强大的选择——也是一个可以提高创造力的选择——是使用框绘图字符设计你自己的角色。
Want a down pointing "caret"? Here's one: ╲╱
想要一个向下的“插入符号”？这是一个：╲╱
I've recently discovered them — and I take great pleasure at using such custom designed characters for labeling things all around :) .
我最近发现了它们——我很高兴使用这种定制设计的字符来标记周围的东西:)。

You might be able to use the black triangles, Unicode values U+25b2 and U+25bc. Or the arrows, U+2191 and U+2193.
您或许可以使用黑色三角形、Unicode 值 U+25b2 和 U+25bc。或者箭头，U+2191 和 U+2193。

c# code
代码
int i = 0;
char c = '↑';
i = (int)c;
Console.WriteLine(i); // prints 8593
int j = 0;
char d = '↓';
j = (int)d;
Console.WriteLine(j); // prints 8595

You might consider using Font Awesomeinstead of using the unicode or other icons
您可能会考虑使用Font Awesome而不是使用 unicode 或其他图标
The code can be as simple as (a) including font-awesome e.g. <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">(b) making a button such as <button><i class="fa fa-arrow-down"></i></button>

I'd use a couple of tiny images. Would look better too.
我会使用几个小图像。也会更好看。
Alternatively, you can try the Character Map utility that comes with Windows or try looking here.
或者，您可以尝试使用 Windows 附带的字符映射实用程序或尝试查看此处。
Another solution I've seen is to use the Wingdings font for symbols. That has a lot fo arrows.
我见过的另一个解决方案是对符号使用 Wingdings 字体。这有很多箭头。
