The doc-string of `read-char' says

    If the character has modifiers, they are resolved and reflected to the
    character code if possible (e.g. C-SPC -> 0).

Do you have a particular use case that calls for throwing an error here?

> Besides, in `char-resolve-modifers', "modifiers" is misspelled.

I fixed that.
