character conversion of 'í' and 'ì' to straight double quotation, instead of 'i'

[unidonburi]

The characters [í] (unicode 205 and 237) and [ì] (unicode 204 and 236) are converted to a double quotation ["].
e.g.:
'écrìture' -> écr"ture
(it should convert to 'écriture', or 'ecriture', right?)

Both of these characters [íì] sometimes appear in old English and/or in OCR mistakes, and should be converted to a standard English [i] character, not a double straight quotation.

Thanks for reporting this. I'll start by verifying & can reproduce, then go from there...
