HTML5 Canvas 中的希腊字母
原标题:Greek Letters in HTML5 Canvas

是否有办法在 HTML 5 画布上打印希腊字母? 我试过使用 html 实体的名称和编号, 像这样

canvas2.cx.fillText("ξ", 50, 50);

canvas2.cx.fillText("ξ", 50, 50);

但它只是打印出来 字面上,因为画布不知道 解释这些符号。

最佳回答

简单地使用UTF-8。

你不必逃避字符 才能用 HTML 或 Canvas 来写

在文档中使用正确的页眉 :

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF8">
问题回答

如果您想要将您的 JavaScript 源限制为 ASCII, 但仍包括在字符串中的非 ASCII 字符, 您可以使用 Unicode 解码序列 :( 小xi 代码点为 U+03BE ) :

canvas2.cx.fillText("u03be", 50, 50);

类似 吗? 如果您重新使用 UTF-8, 您也许可以只键入字符字典。 例如 :

canvas2.cx.fillText("α", 50, 50);
