how to add encoding?

When I start rtf2lrf with
rtf2lrf (calibre 0.4.130)

rtf2lrf --encoding=cp-1251 --keep-intermediate-files z.rtf

It says

Converting XML to HTML...

File "c:\Program Files\calibre\library.zip\calibre\ebooks\lrf\html\ convert_fro
m.py", line 385, in add_file
LookupError: unknown encoding: cp-1251

What's missing for cp-1251 encoding and where I can get it?
What file is it looking for and can I create it myself (assuming I know the relation between cp-1251 codepoints and unicode, but do not know python)?

Thank you.

Does the file library.zip in the calibre install folder contain the file encodings\cp1251.py?

hmm the pyo file is all that should be required.

what does the following command in a terminal give you?
[code]
calibre-debug -c "print 'abc'.decode('cp1251')"

D:\>calibre-debug -c "print 'abc'.decode('cp1251')"
abc

BTW, I might have misspelled cp1251. The following line gives error
rtf2lrf --encoding=cp-1251 --keep-intermediate-files z.rtf

But this line does not, but still does not produce readable result.

D:\>rtf2lrf --encoding=cp1251 z.rtf

Output written to D:\z.lrf

z.rtf is a simple rtf file. It consists of 2 lines of Russian alphabet. It is viewable by both WordPad and WordViewer (not sure about MSWord, do not have one). It is really small, I will post it here:

{\rtf1\ansi\ansicpg1251\deff0\deflang1049\deflangf e1049\deftab708{\fonttbl{\f0\fswiss\fprq2\fcharset 204{\*\fname Arial CYR;}Arial;}{\f1\froman\fprq2\fcharset204{\*\fname Times New Roman CYR;}Times New Roman;}{\f2\fmodern\fprq1\fcharset204{\*\fname Courier New CYR;}Courier New;}}

any2epub test.rtf

works for me. You can then convert the epub to LRF if you want.
