The escaped string should be prefixed with "E" (without a leading space). The current implementation adds " E" with a space, which would result in invalid SQL syntax like " E'...'". This should be "E" + escaped instead of " E" + escaped.

Suggested change

	escaped = " E" + escaped;
	escaped = "E" + escaped;

Missing space after colon in the URL comment. Should be "Taken from: https://..." instead of "Taken from:https://..."
