[Matplotlib-users] Using non ascii characters

[BL <bra...@gm...>]

   Hi,

I would like to use non ascii characters in title and label but with my
current intallation it does not work properly.
There's no warning or error messages when I set a title with some non ascii
characters (I use iso-88599-1 characters, like =E9 or =E0), but I get a emp=
ty
square instead of theses characters in the figure.

I'm using matplotlib-0.90.1.
Is there anything to configure to handle non ascii characters ?

Regards,

This probably depends on the backend you are using.  Which backend and 
on which platform are you having trouble with?  0.90.1 had a number of 
Unicode and non-ascii problems that 0.91.2 resolves.  You may want to 
try that.

Failing that, can you attach a small script that exhibits the problem? 
There may be all kinds of things going wrong, from the encoding of the 
source file, to an incorrect font etc. and an example would help us 
narrow it down.

Cheers,
Mike

Re: [Matplotlib-users] Using non ascii characters

I'm using a basic Debian Etch distribution.
I've attached a very simple file showing the problem. On my computer,
neither the title, nor the legend are displayed correctly, and I've got
square instead of each non ascii characters.

The attached script gives me the following informations :

matplotlib :  0.90.1
backend    :  TkAgg
encoding   :  UTF-8

I will try to install a SVN version of matplotlib and see if this works
better.

To use non-ascii characters, you need prefix the string literal with a 
'u'.  For example:

	u"This is a Unicode string"

Alternatively, you can write out an 8-bit string and then explicitly 
decode it into Unicode:

	unicode("This is UTF-8", "utf-8")

Replacing the r's with u's in the strings in your example solves the 
problem for me on 0.91.2.  (I wasn't able to test 0.90.1 -- that still 
may have internal problems handling Unicode strings in some backends.)

Mike

I thought that the u"string" notation was only needed when characters had to
be handled with their utf-8 code

This works fine for me with the SVN version (matplotlib :  0.98pre) but not
with matplotlib 0.90.1

Thanks
