If multiple locales are given in an {{jsxref("Array")}}, the <a href="https://tc39.github.io/ecma402/#sec-bestavailablelocale">best available locale</a> is used.

+
+<p>The <code>toLocaleUpperCase()</code> method returns the value of the string converted to upper case according to any locale-specific case mappings. <code>toLocaleUpperCase()</code> does not affect the value of the string itself. In most cases, this will produce the same result as {{jsxref("String.prototype.toUpperCase()", "toUpperCase()")}}, but for some locales, such as Turkish, whose case mappings do not follow the default case mappings in Unicode, there may be a different result.</p>
+
+<p>Also notice that conversion is not necessarily a 1:1 character mapping, as some characters might result in two (or even more) characters when transformed to upper-case. Therefore the length of the result string can differ from the input length. This also implies that the conversion is not stable, so i.E. the following can return <code>false</code>:<br>
+ <code>x.toLocaleLowerCase() === x.toLocaleUpperCase().toLocaleLowerCase()</code></p>
