If you're good now, staggers, then you're good.
Whenever you press Ctrl+N and start a new set, by default I believe the character set is "default" which is good. But to access extended characters by their value—what you need to type to create them with your font loaded in Xara, for example—you need to switch the mapping from Name to Decimal from the top left drop-down list.
Here's a chart I made up to provide everyone with the most common extended characters. The PDF is the same, but you can highlight and copy characters from it.
My Best,
Gary
