  Log:
    hash.c: env encoding fallback on Windows
    
    * hash.c (env_str_new, env_path_str_new): make default string
      UTF-8 for the case conversion is not possible.  [Bug #8822]
    * hash.c (get_env_cstr): convert non-ASCII string to UTF-8 string.
    * hash.c (ruby_setenv): use wide char version to put environment
      variable to deal with non-ASCII value.
