Since insider build 17035 and the April 2018 update (nominal build 17134) for Windows 10, a "Beta: Use Unicode UTf-8 for worldwide language support" checkbox is available for setting the locale code page to UTF-8.{{efn|1=Found under control panel, "Region" entry, "Administative" tab, "Change system locale" button.}} However, this option can break "narrow" functions such as <code>fopen()</code> in legacy applications as many of them assume that all MBCS code pages are DBCS (double-byte). In fact, all "locales" available from the control panel dropdown are at most double-byte, and code pages with more bytes such as [[GB 18030]] (cp54936) and [[UTF-8]] has been unavailable for selection from the dropdown list.
