From 211964d56ee00a7d46e251cbc150afb79138ae37 Mon Sep 17 00:00:00 2001 From: Hiltjo Posthuma Date: Tue, 7 Feb 2023 20:00:59 +0100 Subject: [PATCH] ignore C1 control characters in UTF-8 mode Ignore processing and printing C1 control characters in UTF-8 mode. These are in the range: 0x80 - 0x9f. By default in st the mode is set to UTF-8. This matches more the behaviour of xterm with the options -u8 or +u8 also. Also see the xterm resource "allowC1Printable". Let me know if this breaks something, in most cases I don't think so.
