If we enforce UTF-8, we should presumably disallow at the very least U+FFFE and U+FFFF too. C99 contains a list of Unicode characters allowed in C identifiers. I believe we should allow those characters (plus at a minimum -+.#:@) as well, but I'd much rather we didn't make those kinds of decisions for the user. If we have *specific* characters we can't tolerate we should rule them out (like control characters), but even that occationally leads to major frustration on the part of the user: "why can't I use '.' in tag names in CVS"? -hpa - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.htmlReceived on Thu Oct 13 01:48:02 2005
