In some jurisdictions modifying fonts (or any other software) would be considered a consumer right, you bought or otherwise legally obtained it so you can do whatever you want with it unless you make a device violate some other law (sticking rockets onto your car or forcing 30,000 volts down the public phone system would not be legal modifications). In such a jurisdiction you can ignore anything in the license banning personal-use modification, but such a font would still be considered a derived work, which was copyright of both yourself and the original font creator and hence required both your permissions for distribution. Whether this is the case in much of Europe has recently gone from rather- unclear-but-its-probably-legal to rather-unclear-but-its-probably-illegal.
