The crux of the issue, with Unicode -and UTF8 by extension- is that the same character, say, the acute accent "é",  can be represented in different ways, encoding wise, while visually identical. 

This is what people means by "normalization": everyone needs to agree how to encode "é" the same way, so everyone understand what "é" is.

This is a solved problem. But it introduces additional work.
