[issue7260] SyntaxError with a not-existing offset for unicode code

New submission from Noam Raphael <noamraph[at]gmail.com>:

Hello,

This is from the current svn:

> ./python
Python 3.2a0 (py3k:76104, Nov 4 2009, 08:49:44)
[GCC 4.4.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> try:
... eval("u'שלום'")
... except SyntaxError as e:
... e
...
SyntaxError('invalid syntax', ('<string>', 1, 11, "u'שלום'"))

As you can see, the offset (11) refers to a non-existing character, as
the code contains only 7 characters.

Thanks,
Noam

[issue7260] SyntaxError with a not-existing offset for unicode code [In reply to]

Ezio Melotti <ezio.melotti[at]gmail.com> added the comment:

Apparently the position of the caret is based on the number of bytes in
the line, not on the characters:
>>> [aaa for x in]
File "<stdin>", line 1
[aaa for x in]
^
SyntaxError: invalid syntax
>>> [äää for x in]
File "<stdin>", line 1
[äää for x in]
^
SyntaxError: invalid syntax

In this example each ä takes two bytes so the caret is 3 extra chars on
the right.

This is actually a duplicate of #2382, so I'm closing it.
#2382 also has some patch.
