ascii character - removing chars from string

[bruce]

simon...

the issue that i'm seeing is not a result of simply using the
'string.replace' function. it appears that there's something else going on
in the text....

although i can see the nbsp in the file, the file is manipulated by a number
of other functions prior to me writing the information out to a file.
somewhere the 'nbsp' is changed, so there's something else going on...

however, the error i get indicates that the char 'u\xa0' is what's causing
the issue.. as far as i can determine, the string.replace can't/doesn't
handle non-ascii chars. i'm still looking for a way to search/replace
non-ascii chars...

this would/should resolve my issue..

Did you not see this part of the post that you're replying to?

My point was not that '\xa0' is an ascii character... It was that your
initial request was very misleading:

"i'm running into a problem where i'm seeing non-ascii chars in the
parsing i'm doing. in looking through various docs, i can't find
functions to remove/restrict strings to valid ascii chars."

That's why you got three different answers to the wrong question.

You weren't "seeing non-ascii chars" at all.  You were seeing ascii
representations of html entities that, in the case of ' ', happen
to represent non-ascii values.

Simplicity:

s.replace(' ', ' ')
