Everything "looks" fine until you try to extract substrings in some way. That's because without decoding your data on input the strings are handled as sequences of bytes, so a character like translates to two bytes.

Now if you extract some part of string and didn't decoded it first, you can accidentally rip apart these two bytes, leaving behind encoding garbage - usually not a good idea.

So I recommend to properly decode UTF-8 (and other character encodings) during input, and encode the strings on output. And use utf8; if you have string constants in your source code.
