Generate PDF with Tamil font problem

[sath...@e-ndicus.com]

Hi All,

I am using python's reportlab to print some unicode Tamil characters
'பே'. I added necessary unicode font to reportlab. But It
prints the output as 'ேப' (in reverse order). This issue
happens for multi-byte characters, whereas for character 'ப' is
printed as it is.
I am struggling to figure out the issue. Any help would see me on track.

Thank you,

Something similar came up on stackoverflow recently, though that was
with tkinter. Might shed some light.

.......

you can ask at the reportlab mailing list reportl...@reportlab.com; the use
of numeric entities is supported in paragraph text, but not in canvas.drawString
and similar. There you need to use either unicode or a utf8 encoded byte string.

I am also facing the same problem with another similar Indian language- Malayalam. Has anybody encountered such issue and found any solution for this?

You are replying to a six year old message from 2011. I doubt anyone remembers
the details of that discussion.

Please show us a SIMPLE example of this issue.

If I try this, I get something which appears to be okay:

py> print('\u2986\u3015')
⦆〕

but they don't appear to be Tamil characters?

py> for c in '\u2986\u3015':
... unicodedata.name(c)
...
'RIGHT WHITE PARENTHESIS'
'RIGHT TORTOISE SHELL BRACKET'


Let me try this instead:

py> for c in (chr(2986), chr(3015)):
... unicodedata.name(c)
...
'TAMIL LETTER PA'
'TAMIL VOWEL SIGN EE'

That's better!

py> print(''.join([chr(2986), chr(3015)]))
பே


If you want help to diagnose and fix this, you will need to show us some simple
code demonstrating the problem. Also tell us what output you expect, and what
version of Python you are running.
