Gökhan,
I tried your code, and everything worked fine for me. (PythonXY 2.7.3.1 on
Windows 7)
However, I usually use the escaped unicode value rather than unicode
characters directly. Does the following work instead:
fp = plt.figure(figsize=(8.5, 11))
fp.text(0.5, 0.5, uTemperature, \u00B0C, color='black', fontsize=16)
plt.savefig('test.ps', papertype='letter')
plt.savefig('test.pdf', papertype='letter')
Just a thought. Hope it helps.
Ryan
This works fine. However it is easy to remember a superscript o then its
code :) By the way, can you select the text within the PS file?

I just noticed that you are using here the character U+2070 superscript
zero (^(0)) while Ryan's proposition is U+00B0 degree sign (°) which
I think is the correct one to use.
This being said, there should be no difference between using the Unicode
code and actual ° character (and I agree it's simpler to remember)
In [1]: a = uTemperature, \u00B0C
In [2]: a
Out[2]: u'Temperature, \xb0C'
In [6]: b = uTemperature °C
In [7]: b
Out[7]: u'Temperature \xb0C'
Coming back to your other question, I can't select the text in the PS
file (using Okular or Evince). (but PDF is selectable)
Also, the PS file renders properly with both ^(0) and ° signs. (but
with PDF, the ^(0) is placed to low, while ° is fine)
Best,
Pierre

You are right, U+00B0 is the right one. I think, I couldn't find a
superscript o easily then decided to use superscript zero from
http://en.wikipedia.org/wiki/Unicode_subscripts_and_superscripts
However, there is a slight difference in their appearance when I compare
them side by side.
For simplicity, I just use subscript and superscript unicode symbols to
construct simple units.
In [1]: a = uTemperature, \u00B0C
In [2]: a
Out[2]: u'Temperature, \xb0C'
In [6]: b = uTemperature °C

Could you test my outputs if they look fine on your side?
