<div>
<pre>This has been detected by a charactersAreAllASCII() assert failure.
Initially in WebKitForWayland (WPE), but the code was likely borrowed from EFL.
This is because ASCIILiteral() is wrongly used in mediaControlsStyleSheet().
mediaControlsBaseUserAgentStyleSheet is a char array, not a null-terminated string.
It is thus incorrect to use StringImpl::createFromLiteral() that calls strlen() to get the string length.
The String::ConstructFromLiteral constructor can not be used, since it skips the last character.
The size should be explicitly passed to the String constructor.</pre>
