The dollar fell to fresh 7-1/2 month lows against the euro and 3-month lows against the Swiss franc on Wednesday as the greenback's recent slide on the back of weak data gained momentum across the board. By 0730 GMT the euro traded as high as $1.2557 , up 1/4 percent on the day and its highest since late February. The dollar also fell as low as 1.2253 Swiss francs , its lowest since late July and down 1/3 of a percent on the day. "Given recent soft U.S. data, there has been a tendency to buy (the euro) on dips and appetite to test the upside (in the euro)," said Daragh Maher, currency strategist at Calyon.///
