Displaying Unicode Chars

[gregpinero@gmail.com]

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 $B!g(B

Now, this does seem to work:

>>print u"\u221E"

$B!g(B
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)

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.
