   bash# uname -a

   bash# echo $LANG

   bash# which objdump

   bash# objdump --version

   bash# objdump.exe -p npmy.dll

npmy.dll:     Ð¡â€žÐ Ñ•Ð¡Ð‚Ð Ñ˜Ð Â°Ð¡â€š Ð¡â€žÐ Â°Ð â„–Ð Â»Ð Â° pei-i386

I look more carefully on 'objdump' output. It translated partially!
(--version output not translated in general)

My code parse 'objdump -p' output and expect grep some keywords, which 
translated.
To workaround I use:

   $ LC_ALL=C objdump -p my.dll | sed '...'

So there are two issue with binutils:
   * partially translated
   * ignore LANG=ruRU.cp1251 and uses UTF-8
