assuming you have 2.0 or later, something like this
should work:

import unicodedata, string

def maketable():
    # build iso-latin-1 to "undotted" ascii translation table
    table = range(256)
    for i in table:
        x = unicodedata.decomposition(unichr(i))
        if x and x[0] == "0":
            table[i] = int(x.split()[0], 16)
    return string.join(map(chr, table), "")

text = "...some accented iso-latin-1 text..."

noaccents = maketable()

undotted_text = string.translate(text, noaccents)

hope this helps!
