- Description:
- There are plenty of Unicode libraries for C/C++ out there that implement random
Unicode algorithms, but many of them don't handle ill-formed UTF sequences at
all. In the best-case scenario, you'll get an exception/error; in the
worst-case, undefined behavior. The biggest problem is that in 99% cases
everything will be fine. This is inappropriate for security reasons. This
library handles such problems (there are not only ill-formed sequences actually)
properly and always according to The Unicode Standard.
In C/C++, unlike some other programming languages, there is no safe type for
UTF-8/UTF-16 that guarantees that the data will be well-formed; this makes the
problem even worse. The library doesn't introduce such a type either because the
library doesn't work with types/strings/files/streams, it works with the data
inside them and makes it safe when it's needed.
Check this article if you want more information about ill-formed sequences:

It is a bit outdated because ICU (International Components for Unicode) now uses
W3C conformant implementation too, but the information in the article is very
useful.
This library does use W3C conformant implementation too.
