convert charset=binary, grep is not working, linux

I have this situation when I use

cat .rsrc/1033/version.txt

FILEVERSION    8,12,0,2
PRODUCTVERSION 8,12,0,2
FILEFLAGSMASK  0x3F
FILEFLAGS      0x0
FILEOS         VOS_UNKNOWN | VOS__WINDOWS32
FILETYPE       VFT_APP
FILESUBTYPE    0x0
{
  BLOCK "StringFileInfo"
  {
    BLOCK "040904e4"
    {
      VALUE "Comments",          "This installation was built with Inno Setup."
      VALUE "CompanyName",       "Skype Technologies S.A."
      VALUE "FileDescription",   "Skype Setup"
      VALUE "FileVersion",       "8.12.0.2"
      VALUE "LegalCopyright",    "(c) 2017 Skype and/or Microsoft"
      VALUE "ProductName",       "Skype"
      VALUE "ProductVersion",    "8.12"
    }
  }
  BLOCK "VarFileInfo"
  {
    VALUE "Translation", 0x409, 1252
  }
}

When I try to grep line with FileVersion info it will not work:

grep FileVersion .rsrc/1033/version.txt

When I open this file in vi editor:

Turns out I can check file type:

file -bi version.txt

This will show me some kind of binary data:

application/octet-stream; charset=binary

Solution is to use:

iconv -f unicode -t utf-8 version.txt | grep FileVersion
