Suddenly, likely due an update, input is corrupted for ASCII chars. I am using Windows 10 (Version 1803, Build 17134.112).

Usually if I write left Alt + 254 on numeric keyboard I got black square ■ but now I am getting replacement character �. Similar applies to other ones.

Any solutions?

  • What OS? What update? – Spiff Jun 17 '18 at 21:49

  • ■ is what I get when I type in Alt+254 so your updated Windows to version 1803 and then now when you type in Alt+254 now you get the � character instead? Have you already rebooted the PC just in case it's something simple or else wonder what language your system is setup with exactly? – Pimp Juice IT Jun 20 '18 at 0:27
  • This applies to all chars from 128 to, it seems, 255. I am using Czech and secondary English. You can see on asciitable.com that 125 is normally } and 254 is ■. – Ucho Jun 20 '18 at 19:38

The cause was in the setting that I set some day. Specifically, “Use Unicode UTF-8 for worldwide language support”.

  • Huh, that's an interesting setting. (Good idea a few decades late?) – user1686 Jun 25 '18 at 14:37
  • @grawity: I dunno what that should do but definitely on my Windows 10 settings this beta feature works bad. – Ucho Jun 25 '18 at 14:49
