Translate missing on 1.12.30

Dec 31, 2011
I have found a lot of place where translation is missing :

  • Calendar month view show chinese symbol
  • Radio button isn't translate
  • Long press home, button isn't translate
  • Search bar isn't translated
  • Track traffic in Tools isn't translated
  • Notes apps isn't translated

Almost all stuff of MIUI isn't translated, is they any reason for that or it's just a missing ?
