Have you ever tried to open an older program, only to see strange symbols or scrambled text? This happens because some older software cannot read modern character standards. By changing your System Locale, you can help these programs display text correctly.

Why change the System Locale? Some older apps do not use Unicode, which is the global standard for text. Changing this setting acts as a translator so your computer can display the correct characters for those specific programs.

What happens when done? Your computer will be better at reading older software. Note that this change applies to every user account on your PC, not just your own.

  1. Yes, that was what I tought first to do without that little tutorial. But it that not doing that. Also if I want to run a program with another UNICODE language, that do not mean that the whole system must be in the local UNICODE language. So..it is not completly correct and also do not work so simply.

    But thanks..

  2. And sorry for my bad english. I am a little bit stressed becouse my programs from other countries worked under windows 10 perfectly fine and in the upgrade report was nothing written about that there will be unicode system changes.
