In handwritten text, the actual form of the extra marking may vary from a pair of dots to a pair of short vertical bars, to a single horizontal bar, or to a wavy line resembling a tilde. In practice, almost any diacritic situated above the base glyph (for example, "á ā ã") would probably be interpreted as a carelessly written pair of dots ("ä"). However, in computerized character sets, these alternatives are incorrect. The front-vowel counterpart of "u" using the glyph "y" rather than "ü" is carried over from Swedish, and additionally avoids confusion in cursive script with "ii", which is common in Finnish.
