Bug #3180: getc with text mode breaks incomplete character immediately before EOF

• Status: Closed

遠藤です。

coding: UTF-8

"う" の途中で切れた中途半端なファイルを作る

s = "あいうえお".force_encoding("ASCII-8BIT")
open("foo.txt", "wb") {|f| f.write(s[0, 8]) }

IO#read で一気に読めば期待通り

open("foo.txt", "rt") {|f| p f.read } #=> "あい\xE3\x81"

UTF-8 を明示すると UTF-8 になるが、最後の文字が化ける

open("foo.txt", "rt:UTF-8") {|f| p f.chars.to_a }
#=> ["あ", "い", "\u0000\u0000"]

LANG は ja_JP.UTF-8 です。

incomplete な文字が "\0\0" に化けるのは意図的でしょうか。
期待としては、["あ", "い", "\xE3", "\x81"] です。
