I'll admit opening a can of worms on purpose, but if you're going for the "high-end", ignoring the i18n implications seems like a crime on its own, and yet most people don't really have the design expertise to evaluate whether a font looks good in another totally foreign language...
If you take Hebrew, Korean, Georgian, Armenian, Thai, hiragana, katakana, you're in trouble. They all have different proportions, traditions, connections. You can stylize them a bit to be reminiscent of the way the Latin font is made, but you'll have hard time making a Hebrew font with large serifs like Bodoni, and will have hard time making it materially different from Times New Roman in a convincing way. It's better to make a separate typeface.
Arabic / Persian / Urdu, or hanji are their own worlds altogether, hardly comparable to Western typography.
