title: How to avoid inadvertent encoding of UTF-8 files as ASCII/ANSI?
body: <p>In the process of editing a file encoded as UTF-8 w/o [spurious] BOM the content might become devoid of any Unicode characters outside the ASCII or ANSI ranges. At the next reopening of the file, some text editors (Notepad++) will interpret it as ASCII/ANSI encoded and open it as such. Unaware of the change the user will continue editing, now adding non-ANSI Unicode characters, rendered however useless, since saved in ANSI. A menu option can exist (Notepad++) to open ANSI files as UTF-8 w/o BOM, but leading to the reverse issue of inadvertently overriding ANSI files with Unicode encoding.</p>
