Re: Using utf-8 in an application


Here are the questions.

1) In livido.h we #include <wchar.c>

You shouldnt need to include anything.


2) for getting the utf-8 string length in bytes, we use wcslen(). Is this
the correct function ?

No, regular strlen will work fine for utf-8 strings length in bytes.



3) when a string is retrieved, we must add a utf-8 terminating NULL to the
end. How is this done ?

The same as you would with an ascii string- they both use a single 0 byte as a terminating null.



4) For testing purposes, I want to create a utf-8 string. Is there a
simple way to convert a char *string to utf-8 ?

a char* string is a utf-8 string.


Unless you plan on doing fancy things such as normalization etc, you can treat utf-8 strings
like a sequence of null terminated non-null bytes.
