Hello.

I use Sagemath to show the Linear Algebra problems solution.

And I am Korean.

Therefore I write the title in Korean.

But in worksheet, the title is broken because of truncated_name
function in worksheet.py.


def truncated_name(self, max=30):
name = self.name()
if len(name) > max:
name = name[:max] + ' ...'
return name


But Unicode is not 1 byte by character.

So Korean is broken if max is midpoint of Korean one character.

Therefore I modify the function code like this.


def truncated_name(self, max=30):
name = unicode(self.name(), "utf-8") # name = self.name()
if len(name) > max:
name = name[:max] + ' ...'
return name.encode('utf-8') # return name


Now name is encoded by unicode, then Korean one character's length is
1, not 2 or 3.

So I can see the right title.



I think there are more good choice to solve the problem.

Because I don't know about Python well and unicode also.

So I suggest this.
