Inside my python scrip, I get some string back from a function which I didn't write. The encoding of it varies. I need to convert it to ascii format. Is there some fool-proof way of doing this? I don't mind replacing the non-ascii chars with blanks or something else...

UTF-8: It uses 1, 2, 3 or 4 bytes to encode every code point. It is backwards compatible with ASCII. All English characters just need 1 byte — which is quite efficient. We only need more bytes if we are sending non-English characters. It is the most popular form of encoding, and is by default the encoding in Python 3.
For backward compatibility, the first 128 Unicode characters point to ASCII characters. And since UTF-8 encodes each of those characters using 1-byte. ASCII is essentially just UTF-8, or we can say that ASCII is a subset of Unicode.
To decode a string encoded in UTF-8 format, we can use the decode() method specified on strings. This method accepts two arguments, encoding and error . encoding accepts the encoding of the string to be decoded, and error decides how to handle errors that arise during decoding.
If you want an ASCII string that unambiguously represents what you have got, without losing any information, the answer is simple:
Don't muck about with encode/decode, use the repr() function (Python 2.X) or the ascii() function (Python 3.x).
