EVERY keyboard world-wide generates EXACTLY the same key-position-codes. The only difference with any language-specific keyboard is that the key CAPS (ONLY) are etched with language-specific characters, in addition to English characters.
This is still true for Arabic and Chinese.
ALL the work of language specialization is done inside the Mac, mainly with the "input Sources" also known as keyboard translation tables.
When you ask for a language-specific keyboard, ONLY the Glyphs on the plastic key caps are changed, and NOTHING else. If you could use a Typing chart on the wall, or the Keyboard Viewer in the Mac, or put stickers on the keys or mark them with a sharpie marker, you would obtain the same effect, just slightly less visually appealing.
NB>> prices quoted in the US are NET of State Sales taxes, which are added to your bill at payment-time. US State tax in New York is at least 8 percent, and if you take delivery in New York City, City tax adds about another 0.875 percent, so almost nine percent total. NOT optional, and not refundable. The rate is based on WHERE the goods are delivered to you, not where you will use them..
