notebook -- improve UNICODE handling of truncated_name function in worksheet.py #6477
Description
From NoSyu <[email protected]>
Hello.
I use Sagemath to show the Linear Algebra problems solution.
And I am Korean.
Therefore I write the title in Korean.
http://nosyu.pe.kr/attach/1/5682987737.png
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.
