def rmdiacritics(char):
    '''
    Return the base character of char, by "removing" any

    '''
    desc = ud.name(unicode(char))
    cutoff = desc.find(' WITH ')
    if cutoff != -1:
        desc = desc[:cutoff]
    return ud.lookup(desc)

def removeAccents(feature):
    attribute_list = ("name", "type", "state") # Modify as needed
    for attrib in feature.getAllAttributeNames():
        if attrib in attribute_list:
            value = feature.getAttribute(attrib)
            if value:
                value = unicode(value)
                new_value = ''.join([rmdiacritics(char) for char in value])
                feature.setAttribute(attrib, new_value)
