Summary: repr diff between string and unicode.

Initial Comment:
A minor difference exists between the repr output of 
string and unicode.

>>> "\x7f"
'\x7f'
>>> u"\x7f"
u'⌂'
>>>

I can't think of any reason for this difference.

Ah, now I understand... I was misinterpreting the SF comment
which probably got passed through some HTML-quoting function.

You are right, \x7f should also be quoted. 
I'll fix that in CVS.

I used 2.2b2. I had though the code in unicodeescape_string 
was at fault since it does:

        /* Map non-printable US ASCII to '\xhh' */
        else if (ch < ' ' || ch >= 128) {
            *p++ = '\';
            *p++ = 'x';
            *p++ = hexdigit[(ch >> 4) & 0x000F];
            *p++ = hexdigit[ch & 0x000F];
        }

where as string_repr does:

                else if (c < ' ' || c >= 0x7f) {
                        sprintf(p, "\x%02x", c & 0xff);
                        p += 4;

The 0x7F character is treated differently. I can't compile 
C programs at the moment so I cant verify this on the CVS 
version.

I can't reproduce this with the current CVS version of
Python on Linux.

Which version did you use ?
