在Python中打印所有unicode字符

Question

我已经编写了一些代码来创建十六进制系统的所有4位数组合,现在我正在尝试使用它来打印出与这些值相关联的所有unicode字符.这是我用来执行此操作的代码:

char_list =["0","1","2","3","4","5","6","7","8","9","A","B","C","D","E","F"]
pairs = []
all_chars = []

# Construct pairs list
for char1 in char_list:
    for char2 in char_list:
        pairs.append(char1 + char2)

# Create every combination of unicode characters ever
    for pair1 in pairs:
        for pair2 in pairs:
            all_chars.append(pair1 + pair2)

# Print all characters
for code in all_chars:
    expression = "u'\u" + code + "'"
    print "{}: {}".format(code,eval(expression))

以下是我收到的错误消息:

Traceback (most recent call last): File "C:\Users\andr7495\Desktop\unifun.py", 
line 18, in <module> print "{}: {}".format(code,eval(expression))
UnicodeEncodeError: 'ascii' codec can't encode character u'\x80' in position 0: 
ordinal not in range(128)

当代码尝试打印u"\ u0080"时抛出异常,但是,我可以在交互式解释器中执行此操作而不会出现问题.

我已经尝试将结果转换为unicode并指定忽略错误,但它没有帮助.我觉得我缺少对unicode如何工作的基本理解,但是我能做些什么来让我的代码打印出所有有效的unicode表达式？

import sys
for i in xrange(sys.maxunicode): 
  print unichr(i);
