basic.lval.11 says, that:

If a program attempts to access the stored value of an object through a glvalue whose type is not similar ([conv.qual]) to one of the following types the behavior is undefined:

• the dynamic type of the object,
• a type that is the signed or unsigned type corresponding to the dynamic type of the object, or
• a char, unsigned char, or std​::​byte type.

so we can access the value of any object with char, unsigned char and std::byte types.

However we cannot provide storage with use of char:

intro.object.3 says, that:

If a complete object is created ([expr.new]) in storage associated with another object e of type “array of N unsigned char” or of type “array of N std​::​byte” ([cstddef.syn]), that array provides storage for the created object if:

Is this asymmetry intended?
Shouldn't intro.object.3 sound like:

If a complete object is created ([expr.new]) in storage associated with another object e of type “array of N unsigned char” or type "array of N char", or of type “array of N std​::​byte” ([cstddef.syn]), that array provides storage for the created object if:
