Help > Can I upload a hand in another language?
We currently don't have support for uploading hands in other languages, however you can still upload your hands by doing the following.
If your client is set to another language and your hand history does not upload to the Replayer then you can request the hand history be emailed to you in English and then upload that file.
You can request the hand history by going to Tools > History & Stats > Get Hand History. Once there enter the hand number you wish to upload and make sure to select English as the language and PokerStars will email you that hand in English which you can upload to the Replayer.
