WebJul 5, 2024 · The type []const u8 is 10 characters long and there are approximately ~1000 occurrences of it in std alone. In most cases it means a UTF-8 encoded string, in the rest it means a u8/byte buffer to read from. It's probably not very hard to figure out the meaning from the context (the surrounding function/struct name) but it takes a tiny bit of effort.

If that don't work, try maybe using \u1234 with 1234 being a code point value. You can also try to use UTF8-CPP maybe. Take a look at this answer : Using Unicode in C++ source code. WebJul 14, 2024 · I presume because u8 matches the underlying type, a text in utf-8. Signedness does not make much sense in the context of a text character - and I agree. So we can go from String to Vec, borrow mutably and get a pointer to it, which always leaves us with *const u8 or *mut u8.
