That seems to be a rather rash statement. I have software (BabelPad) which parses the numeric values of characters for numeric sorting purposes, and it parses "6/12" for MEROITIC CURSIVE FRACTION SIX TWELFTHS as 0.5. Personally I find it hard to imagine how you could write software that accepts "6/12" as input and is unable to come up with the answer of a half. I would say that fractions should not be reduced to their lowest form in the Unicode data as some people may need to order fractions by numerator or denominator, and reducing to lowest form could break the expectations of some software. Having said that, I note that the numeric value of one character has been reduced in the Unicode data: U+2189 VULGAR FRACTION ZERO THIRDS is given the numeric value of "0" rather that "0/3".
