This bug manifests (at least) in windows, when using a font ordering so that western text is styled in Times/Times New Roman, and Japanese text is styled using "MS Mincho", a specifically Japanese CJK font.
<style>
p {
font-family: "Times New Roman", Times, "MS Mincho";
}
</style>
The following word should use MS Mincho: 日本語 -- however, Opera seems to ask the OS to perform font resolution, rather than asking whether the font supports the character and moving on to the next font if it doesn't. I see the previous Japanese word rendered using a Chinese font in Opera.
The following image shows what it should look like (Chrome, Firefox, IE9 and Safari render it correctly) on top, and what Opera 11.60 does instead, at the bottom.
