RTF import read every 8-bit byte as Windows-1252, so Cyrillic (and any
other non-Western) RTF came out as mojibake. Bytes now decode in the
current font's code page (\fcharset, \cpg), else the default font's,
else the document's (\ansicpg), for the single-byte Windows code pages
874 and 1250-1258.
A .doc, .docx or .rtf whose content is another of these formats now opens
by its signature, as Word does: RTF saved as .doc (hh.ru résumés and
accounting exports are commonly saved that way), a .docx renamed .doc, a
Word 97-2003 file renamed .docx.
