Hello, I recently tried this and tried converting a Swedish dictionary to UTF-8 to no avail. When I looked into the bundled UK English and US English dictionaries I saw that they are encoded in ISO8859-1, not UTF-8.

Turns out the bundled en_US.dic and en_UK.dic spell checks fail on words with accented characters, like Föhn, Göteborg, smörgåsbord, Velásquez, even though said words are included in the dictionaries. Changing the encoding of the dics and the SET parameter of the .aff file to UTF-8 does not fix the issue. Seems to me that the bug is not fixed, or am I doing something wrong?
