+Subject: [PATCH] backends/native: Translate keycodes with
+ xkb_key_state_get_one_sym()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+There's two aspects from its documentation
+(https://xkbcommon.org/doc/current/group__state.html#gae56031a8c1d48e7802da32f5f39f5738)
+affecting us here:
+
+1. "This function is similar to xkb_state_key_get_syms(), but intended for
+    users which cannot or do not want to handle the case where multiple
+    keysyms are returned (in which case this function is preferred)."
+
+   We are indeed in that field, and have been for a long time.
+
+2. "This function performs Capitalization Keysym Transformations."
+
+   This is unlike the xkb_key_get_syms() function that we use, and
+   convenient here for parity with X11 since it behaves exactly that
+   way.
+
+Fixes cases where the keysym for some keys is not properly capitalized
+when caps lock is toggled, due to the output of capslock+key being
+different from shift+key. An example of this is 'é' in french(azerty)
+layout (bound to the '2' key). Even though shift+2 outputs '2',
+capslock+é should output 'É'.
