在 wxPython 中使用 unicode 字符
当我尝试插入 unicode 字符时，我对 wxpython 和他的富文本控件有问题... \xb2 打印顶点'2'，'\u2074' 应该打印顶点'4'...
编辑：我使用 Windows Vista...并且我尝试了“编码 cp1252”和“utf-8”，但结果相同...
2编辑： 在vista上它崩溃了，在xp上它显示了一个奇怪的方块（我猜这是当电脑无法识别该字符时...）
这是源代码：
from __future__ import unicode_literals
import wx
import wx.richtext as rt
class Trial(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, -1, 'Prova',
size=(400, 400))
self.rtc = rt.RichTextCtrl(self, style=wx.VSCROLL|wx.HSCROLL|wx.NO_BORDER)
wx.CallAfter(self.rtc.SetFocus)
#self.rtc.Freeze()
self.rtc.BeginFontSize(14)
self.rtc.WriteText('hei!\xb2') #alright
self.rtc.WriteText('hi\u2074!')#crash
self.rtc.EndFontSize()
if __name__ == '__main__':
app = wx.PySimpleApp()
frame = Trial()
frame.Show()
app.MainLoop()
但是当我尝试运行它时，它崩溃了...
Traceback (most recent call last):
File "<pyshell#6>", line 1, in <module>
frame = display.Trial()
File "C:\Users\expert\Desktop\display.py", line 15, in __init__
self.rtc.WriteText('hi\u2074!')
File "C:\Python26\lib\site-packages\wx-2.8-msw-ansi\wx\richtext.py", line 2507, in WriteText
return _richtext.RichTextCtrl_WriteText(*args, **kwargs)
File "C:\Python26\lib\encodings\cp1252.py", line 12, in encode
return codecs.charmap_encode(input,errors,encoding_table)
UnicodeEncodeError: 'charmap' codec can't encode character u'\u2074' in position 4: character maps to <undefined>
所以。 ..我应该怎么办？我真的需要展示它...
谢谢大家！！
i have a problem with wxpython and his rich text control, when I try to insert unicode characters... \xb2 prints an apex '2', '\u2074' should print an apex '4'...
edit: I use windows vista... and I tried 'coding cp1252 ' and 'utf-8' but with the same result...
2edit:
on vista it crashs, on xp it shows a strange square (i guess it's when the pc doesn't recognize the character...)
here is the source code:
from __future__ import unicode_literals
import wx
import wx.richtext as rt
class Trial(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, -1, 'Prova',
size=(400, 400))
self.rtc = rt.RichTextCtrl(self, style=wx.VSCROLL|wx.HSCROLL|wx.NO_BORDER)
wx.CallAfter(self.rtc.SetFocus)
#self.rtc.Freeze()
self.rtc.BeginFontSize(14)
self.rtc.WriteText('hei!\xb2') #alright
self.rtc.WriteText('hi\u2074!')#crash
self.rtc.EndFontSize()
if __name__ == '__main__':
app = wx.PySimpleApp()
frame = Trial()
frame.Show()
app.MainLoop()
but when I try to run it, it crashs...
Traceback (most recent call last):
File "<pyshell#6>", line 1, in <module>
frame = display.Trial()
File "C:\Users\expert\Desktop\display.py", line 15, in __init__
self.rtc.WriteText('hi\u2074!')
File "C:\Python26\lib\site-packages\wx-2.8-msw-ansi\wx\richtext.py", line 2507, in WriteText
return _richtext.RichTextCtrl_WriteText(*args, **kwargs)
File "C:\Python26\lib\encodings\cp1252.py", line 12, in encode
return codecs.charmap_encode(input,errors,encoding_table)
UnicodeEncodeError: 'charmap' codec can't encode character u'\u2074' in position 4: character maps to <undefined>
so...what should I do? I really need to show it...
thanks everybody!!

如果你想要 Unicode 支持，那么你应该使用 wxpython 的 unicode 版本。
大多数其他平台也有两个版本。
如果您传递实际符号，则效果很好，例如
If you want Unicode support then you should be using the unicode version of wxpython.
Most other platforms also have two versions.
It works fine if you pass the actual symbols e.g
如果您忘记设置编码，有时会发生这种情况。将其放在代码顶部：
在任何包含注释的代码之前，但在 shebang 之后 (#!/usr/bin/python)
This can sometimes occur if you forget to set your encoding. Put this at the top of the code:
before any code including comments but after the shebang (#!/usr/bin/python)
