What exactly do you mean by "convert an integer to a dchar"?  Do you
mean converting an integer between 0 and 9 into a dchar representing its
digit value, or do you mean creating a dchar containing the unicode code
point represented by the int?

For the former:

	dchar ch = '0' + intValue;

(Though you will have to consider what should happen if intValue > 9.)

For the latter:

	dchar ch = cast(dchar) intValue;
