From e85727ddb68b3b23382ea2d78d857ffa870bb0b7 Mon Sep 17 00:00:00 2001 From: Masahisa Kojima Date: Sun, 29 May 2022 10:52:43 +0900 Subject: [PATCH] bootmenu: use utf-8 for menu title The commit a3d0aa87acbe ("bootmenu: update bootmenu_entry structure") changes the bootmenu title type from char to u16(UTF16 string) to support EFI based system. If EFI_LOADER is not enabled, printf("%ls") is not supported, so bootmenu does not appear correctly. This commit changes the type of menu title from u16(UTF16) to utf-8 string and EFI strings is conveted into utf-8.
