The workaround in your case is:

in the beginning of your program:

import sys
if hasattr(sys.stdin, 'encoding'):
    console_encoding = sys.stdin.encoding
else:
    import locale
    locale_name, console_encoding = locale.getdefaultlocale()

and later:

uni = unicode(word, console_encoding)

But don't think it's portable, if you use other IDE or OS, it may not
work. It would be better if PyDev implemented sys.stdin.encoding
