python-enchant-crash.py
It crashes, because python3-enchant crashes:
$ python3 python-enchant-crash.py
['Budapest', 'Budapesti', 'Budapesté', 'Budapestű']
[b'Budapest', b'Budapesti', b'Budapest\xc3\xa9',
b'Budapest\xc5\xb1']

python3-enchant probably crashes because of this problem in hunspell:
$ hunspell -d hu_HU -i utf-8 -l hunspell-conversion-problem.txt

Of course the file converts to UTF-16 just fine:
$ iconv -f utf-8 -t utf-16 < hunspell-conversion-problem.txt | iconv -f utf-16
-t utf-8

It looks like hunspell has problems with characters above the BMP (Basic
Multilingual Plane).

It works on current rawhide with hunspell-1.4.1:
[mfabian@Fedora-Workstation-netinst-x86_6 ~]$ cat /etc/fedora-release
Fedora release 26 (Rawhide)
[mfabian@Fedora-Workstation-netinst-x86_6 ~]$ python3 python-enchant-crash.py
['Budapest', 'Budapesti', 'Budapesté', 'Budapestű']
[b'Budapest', b'Budapesti', b'Budapest\xc3\xa9',
b'Budapest\xc5\xb1']

[mfabian@Fedora-Workstation-netinst-x86_6 ~]$ rpm -q hunspell

Good to know the big rework of stuff in hunspell had a practical worthwhile
effect. I'll have to bisect to find when it started working to see what exactly
was the cause to see if its backportable in isolation.
