I think what Jan is alluding to is the property of UTF-8 text that you can start in the middle of a string and either skip an incomplete character or find the beginning of it. If you can search backwards, you can find the beginning of an escape sequence, too; the "skip incomplete" functionality is missing, though, but as you say, isn't actually all that useful in real life *for the applications which use these kinds of escape sequences.* -hpa -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
