在pyx画布中插入unicode文本 [英] Inserting a unicode text into pyx canvas

问题描述

我有一组UTF-8字符，我想插入一个 PyX 生成的pdf文件。
我已经将＃ - * - 编码：utf-8 - * - 添加到文件的顶部。代码有点类似于以下内容：

I have a set of UTF-8 characters that I would like to insert into a PyX generated pdf file. I have included # -*- coding: utf-8 -*- to top of the file. The code is somewhat similar to the following:

# -*- coding: utf-8 -*-
c = canvas.canvas()
txt = "u'aあä'"
c.text(2, 2, "ID: %s"%txt)
c.writeEPSfile("filename.eps")

但我仍然无法让我的头脑。

But I still can't get my head around this.

错误：

'ascii' codec can't encode character u'\xae' in position 47: ordinal not in range(128)

推荐答案

也许你可以从babel包中找到一个相同的设置
当我尝试插入德语ä（一个umlaut）时，我遇到同样的错误。我只是添加了德国的巴贝包：

Maybe you can find an according set from the babel package I ran into the same error when I tried to insert the german ä (a umlaut). I simply added the german babel package:

text.preamble(r"\usepackage[ngerman]{babel}")

之后，这是可能的，没有错误：

After that, this was possible without errors:

c.text(12, 34, "äöüßß")

我也使用了一个utf8输入编码，我认为这是必要的。

I also used an utf8 input encoding, I think this it is necessary as well.
