Python unescape javascript escapped UTF8 sequence

尋找這種答案很浪費生命，記錄下來

print "".join([(len(i)>0 and unichr(int(i,16)) or "") for i in url.split('%u')])

簡體 UTF8 -> 繁體/正體 UTF8

Encode-CNmap 是好朋友
雖然字表沒有完整，但是大部份都有轉換成功，而且使用上也不錯簡單
轉換文字檔案:
cnmap -u2cb5 utf8.txt > utf8-cntrad.txt

對於懶得在 Python 下面 implement 繁簡轉換的人(me?)實在很好用:

import commands
s = commands.getoutput("echo '简体中文' | cnmap -ucb5")
print s

說真的，這方法最好別用 XD
