Somewhat strange question. Why does e.g. C# support this? Maybe you should ask MS that? Most Unicode characaters are not available on most keyboards. For example, I have a Swedish keyboard. To enter a "Φ" (U+03A6), I will need to find it in Windows character table app (browse, browse, browse...) or find it on the Internet, like I did this time and copy+paste. And even then you just might stumble upon problems with the connection character set having limitations (unless you're using UTF8, which I always do myself unless using ISQL from command line) or your terminal's or editor's character set limitations. Furthermore, there are loads of non printable characters and characters that are difficult to see in a normal text editor, e.g. U+2000..U+200F. I wouldn't want those to appear in an SQL script. I would much prefer a notation where I can see the codepoint. Wouldn't you? Maybe you don't care about readability in your code? Regards, Kjell
