Displaying Unicode Chars

I want to make a little Python utility where a user can enter the
unicode numerical code and get the actual symbol back in utf-8.

For example, a user could enter something like u221E

And get back ∞

Now, this does seem to work:
>>print u"\u221E"

However how can I change it so it works with a string variable?

print unicode("\u221E ") doesn't seem to do it.

I hope this makes sense. I don't know all the unicode terminology to
phrase this question coherently ;-)

Thanks in advance,

Greg

Sure, that's because \u only works in unicode strings. You'd need
to "encode" your \u-containing string to a unicode string. Perhaps
this'll help:
>>def to_unicode(num) :
.... character = "\\u"+num
.... return character.decod e("unicode-escape")
....
>>to_unicode("2 21E")
u'\u221e'
>>print to_unicode("221 E")


(improvements welcome)

Bjrn

Thanks to both of you. Those approaches make sense. Here's the final
result if you're curious:

Not sure what operating system you are using. On Windows, I recommend
that you look at the charmap.exe utility. On Linux, try gucharmap
or kcharselect.

Or gnome-character-map if using Gnome.

I have a file which has no BOM and contains mostly single byte chars. There are numerous double byte chars (Japanese) which appear throughout.

Surely there is an easy way to convert these mixed...

I'm trying to write a basic tool to convert strings to unicode encodings. Should be easy enough, I can do the encoding bit with the various encoding tools in C#, but what I can't seem to do is force C# to spit out the encodings - everything I've done just seems to decode the unicode and spit out exactly what I had typed in. How do I go from a byte of unicode bytes to a string? (As you might guess, I'm not really much of a coder - even...

Hello, I'm writing an class library that I imagine people from different countries might be interested in using, so I'm considering what needs to be provided to support foreign languages, including asian languages (chinese, japanese, korean, etc). First of all, strings will be passed to my class methods, some of which based on the language (and on the encoding) might contain characters that require more that a single byte.
