I'm guessing that the answer probably is in fact No. If you really want to see what it looks like in at least pseudo-uncials, you could copy a section of text, paste it into a word processor, and use the word processor's case-change function to make it all caps. E.g., in Word, select the text and then on the Home tab click the Aa button (Change Case) and select UPPERCASE. In Nota Bene, select the text and then on the Edit menu select Case > Change to Uppercase; or, more simply, hold down Ctrl+Shift+Alt and hit the spacebar to uppercase the selection. You might even do a global find-and-replace to remove all the spaces.
