如何从数字中打印原始UTF-8字符? [英] How do you print raw UTF-8 characters from their numbers?

问题描述

说我想从U+00FF的Unicode/UTF-8编号或c3 bf的十六进制打印一个ÿ(带小写字母的拉丁字母y). 如何在PHP中做到这一点?

Say I wanted to print a ÿ (latin small y with diaeresis) from its Unicode/UTF-8 number of U+00FF or hex of c3 bf. How can I do that in PHP?

原因是我需要能够创建某些UTF-8字符，以便在我的正则表达式和字符串函数中进行测试.但是，由于我的键盘上的键少于200个，所以我无法键入，而且由于很多次我只能停留在ASCII唯一的世界中，因此我需要能够仅基于基数来创建它们 ASCII安全的UTF-8字符代码.

The reason is that I need to be able to create certain UTF-8 Characters is for testing in my regex and string functions. However, since I have less than 200 keys on my keyboard I can't type them - and since many times I am stuck in an ASCII only world - I need to be able to create them bases solely off of their ASCII safe, UTF-8 character code.

注意:为了使它在浏览器中正确显示，我知道第一步是

header('Content-Type: text/html; charset=utf-8');
