/**
* Wrapper for checking IniGetWrapper::getString return value for "effectively UTF-8".
*
* Since PHP 5.6.x, PHP wants mbstring.http_input and mbstring.http_output to be blank,
* so that they will inherit default_charset. IniGetWrapper::getString itself returns
* NULL if a setting did not exist. But we can also see PHP itself return an empty string
* when the PHP.INI contains no reference to one of these settings.
*
* So we're going to account for three cases here, and consider that "all of them mean
* we're about to get the UTF-8 encoding behavior that phpBB requires." First is for
* either NULL or an empty string, either of which would represent a system configured
* per PHP documentation to "leave this setting blank."
*
* But we will also accept "UTF-8" or "utf-8". Not just because this is explicitly required
* for checking default_charset, but also because if either mbstring.http_input or
* mbstring.http_output were explicitly configured to this, phpBB is still getting the
* "PHP will use UTF-8" behavior intended. Creating a warning "just because they didn't
* get there with a blank value" doesn't make things better, and may not be a setting
* that the user can change in order to eliminate the unnecessary warning.
*
* @param string $config Value returned from IniGetWrapper::getString() to be examined.
*
* @return bool True (warning should be presented) if the configuration value
* was not effecitvely "UTF-8". Else false (no warning to be shown).
