Using IO#each_codepoint together with IO#ungetc causes an unwanted exception when encoding conversion is active.

C:\>ruby -e "open('NUL', 'rt') { |f| f.ungetc('aa'); f.each_codepoint { |c| p c }}"
97
-e:1:in 'IO#each_codepoint': byte oriented read for character buffered IO (IOError)
        from -e:1:in 'block in <main>'
        from -e:1:in 'Kernel#open'
        from -e:1:in '<main>'

Fixes [Bug #21131]
