There was a problem hiding this comment.
There is a safe helper CharCast and UCharCast, that can be used.
Though, I have a patch (Bundle 2/2 of #21969) to remove char completely.

…alize fa5d2e6 Remove unused char serialize (MarcoFalke) fa24493 Use spans of std::byte in serialize (MarcoFalke) fa65bbf span: Add BytePtr helper (MarcoFalke) Pull request description: This changes the serialize code (`.read()` and `.write()` functions) to take a `Span` instead of a pointer and size. This is a breaking change for the serialize interface, so at no additional cost we can also switch to `std::byte` (instead of using `char`). The benefits of using `Span`: * Less verbose and less fragile code when passing an already existing `Span`(-like) object to or from serialization The benefits of using `std::byte`: * `std::byte` can't accidentally be mistaken for an integer The goal here is to only change serialize to use spans of `std::byte`. If needed, `AsBytes`, `MakeUCharSpan`, ... can be used (temporarily) to pass spans of the right type.
