I'm having a problem (Python 2.4) converting strings with random 8-bit
characters into an escape form which is 7-bit clean for storage in a database.
Here's an example:
body = meta['mini_body'].encode('unicode-escape')
when given an 8-bit string, (in meta['mini_body']), the code fragment above
yields the error below.
'ascii' codec can't decode byte 0xe1 in position 13: ordinal not in range(128)
the string that generates that error is:

I've read a lot of stuff about Unicode and Python and I'm pretty comfortable
with how you can convert between different encoding types. What I don't
understand is how to go from a byte string with 8-bit characters to an encoded
string where 8-bit characters are turned into two character hexadecimal
sequences.
I really don't care about the character set used. I'm looking for a matched
set
of operations that converts the string to a seven bits a form and back to its
original form. Since I need the ability to match a substring of the original
text while the string is in it's encoded state, something like Unicode-escaped
encoding would work well for me. unfortunately, I am missing some knowledge
about encoding and decoding. I wish I knew what cjson was doing because it
does
the right things for my project. It takes strings or Unicode, stores
everything
as Unicode and then returns everything as Unicode. Quite frankly, I love to
have my entire system run using Unicode strings but again, I missing some
knowledge on how to force all of my modules to be Unicode by default
any enlightenment would be most appreciated.
