Thanks! I've decided to use your library and ended up with almost the same 
script
https://github.com/msalau/hyph-be/blob/master/showhyphens.rb
It accepts words either as arguments or from stdin.

This is the hard part :) All combinations (both possible and impossible) take 
really huge amount of space. I'm considering parsing the hunspell dictionary to 
get only possible combinations.

Thanks. I'll reconsider that part.

Recently I tried patterns with real TeX documents: 
https://github.com/msalau/hyph-be/tree/master/test-doc
I have 2 variants: for T2A encoding (compiled with pdflatex) and for UTF-8 
(compiled with xelatex).

Here is what I've got:

1. document.t2a.tex is an UTF-8 document, uses babel (Belarusian is supported) 
and T2A encoding and is compiled with pdflatex.
Hyphenation works, but output from \showhyphens{} is unreadable:

> [] \T2A/cmr/m/n/10 ��-�-���� ��-��-����!

2. document.tex is an UTF-8 document, uses polyglossia and is compiled with 
xelatex.
Polyglossia doesn't support Belarusian.
Hyphenation doesn't work but output from \showhyphens{} is readable.

If polyglossia is replaced with babel, hyphenation starts to work in the 
document, but not in log:

> Underfull \hbox (badness 10000) in paragraph at lines 10--10

Polyglossia is actually aware of presence of hyphenation patterns for 
Belarusian, since it doesn't complain much.
Here is how it complains about totally unknown language:

> Package polyglossia Warning: File gloss-foo-bar.ldf does not exist!
> (polyglossia)                I will nevertheless try to use hyphenation 
> patterns for foo-bar. on input line 7.

> Package polyglossia Warning: \setlocalhyphenmin useless for unknown language 
> foo-bar on input line 7.

> Package polyglossia Warning: No hyphenation patterns were loaded for `Foo-bar'
> (polyglossia)                I will use \language=\l@nohyphenation instead on 
> input line 7.

Does anyone have any ideas about polyglossia? As I can see, polyglossia can 
access hyphenation patterns
(it know that they exist), but fails to load them for unknown reason.

Best regards,
Maksim.
