QString::fromUtf8 problems converting micro sign

[smacchia]

I am trying to convert the unicode micro-sign to use in a QString. I have tried the following:

QByteArray b(1, 0xb5);
QString s = QString::fromUtf8(b.constData(), b.length());

QByteArray b(1, 0xb5);
QString s = QString::fromUtf8(b.constData(), b.length());

To copy to clipboard, switch view to plain text mode 

But the string isn't the micro-sign but a question mark in a circle.
I also tried:

QChar c(181);
QString s(c);

QChar c(181);
QString s(c);

To copy to clipboard, switch view to plain text mode 

With the same result.
When using this with PyQt:

b = QByteArray(1, "\xb5")
s = QString.fromUtf8(b.data(), b.length())

b = QByteArray(1, "\xb5")
s = QString.fromUtf8(b.data(), b.length())

To copy to clipboard, switch view to plain text mode 

or

c = QChar(181);
s = QString(c);

c = QChar(181);
s = QString(c);

To copy to clipboard, switch view to plain text mode 

both c and b when I print them are also the question mark in the circle. When I try to convert to a QString I get the following error from the python interpreter:

UnicodeEncodeError: 'ascii' codec can't encode character u'\xb5' in position 0:ordinal not in range(128)

UnicodeEncodeError: 'ascii' codec can't encode character u'\xb5' in position 0:ordinal not in range(128)

To copy to clipboard, switch view to plain text mode 

I have tried a variety of combinations and googled everywhere for an adequate solution, to no avail.

FWIW, the python string conversion works as I'd expect, but I need a QString:

>> s  = unichr(181).encode("utf8")
>> print s
>> µ
>> print QString(s)
Traceback (most recent call last):
  File "<input>", line 2, in <module>
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)

>> s  = unichr(181).encode("utf8")
>> print s
>> µ
>> print QString(s)
Traceback (most recent call last):
  File "<input>", line 2, in <module>
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)

Any help with this is greatly appreciated.
