- There will never be any implicit conversion from or to Binary Strings.
- The setting unicode.from_error_subst_char can be used to specify a hex value that should be used if a character can not be converted.
Autoconversion of strings:
<?php
$native = (string) "blåbær";
var_inspect($native);
echo "<br/>\n";
$native .= "øl";
var_inspect($native);
