+======
+
+Description
+-----------
+This patch adds a new terminal mode, /NOWIDE/. If it's enabled, wide characters
+will be replaced with a faint question mark. This mode can be enabled or
+disabled by default with the `renderwide` variable in `config.def.h`, and can be
+toggled with a keybind (`Ctrl+Shift+W` by default).
+
+This mode is specially useful if your font doesn't support wide characters,
+since rendering them usually makes the terminal really, really slow, specially
+when scrolling.
+
+This patch is intended for ST 0.8.2, but it should be easy to port it to newer
+versions.

+Subject: [PATCH] Allow user to not render wide characters
+
+This patch adds a new terminal mode, NOWIDE. If it's enabled, wide characters
+will be replaced with a faint question mark. This mode can be enabled or
+disabled by default with the `renderwide' variable in <config.def.h>, and can be
+toggled with a keybind (Ctrl+Shift+W by default).
+
+This mode is specially useful if your font doesn't support wide characters,
+since rendering them usually makes the terminal really, really slow, specially
+when scrolling.
+
+This patch is intended for ST 0.8.2, but it should be easy to port it to newer
+versions.
