0x0 から 0xff の範囲のバイトに対して mb_convert_encoding が無効なバイトをどのように置き換えるのかを確認します。
<?php
$enc = "cp932";
for ($cp = 0; $cp < 0x100; $cp++) {
$c = chr($cp);
$ret = mb_convert_encoding($c, $enc, $enc);
echo
bin2hex($c), " ",

ラウンドトリップが保障されない文字を調べます。
def chr_unsafe(cp, enc)
[cp.to_s(16)].pack("H*").force_encoding(enc)
end
enc = 'cp932'
count = 0
count2 = 0
(0x8000..0xffff).each do |cp|
