build.cmd

@echo off
REM openMouse - MSVC build.
REM Usage: build.cmd [output-name.exe]
REM
REM Keep this file pure ASCII. cmd.exe reads batch files in the OEM codepage,
REM so a stray UTF-8 character corrupts the whole script, not just its comment.
REM
REM /utf-8 is required: the sources ARE UTF-8, without a BOM. Without the flag
REM MSVC decodes them as the system ANSI codepage and every non-ASCII character
REM becomes mojibake - inside wide L"..." literals too, so it reaches the tray
REM menu and the log, not only narrow text.
