Hi All, We tried to upgrade Mailman from v. 2.1.9 to v. 2.1.20 (default for Ubuntu 16.04) and discovered that for Russian language, mailman scripts tuned the browsers to receive UTF-8 encoded text. How can we turn mailman back to KOI8-R? Our problem is that Russian symbols take 2 bytes each in UTF-8. We do not want to inflate our lists twice. We want to use UTF-8 _only_ for very mixed (English/Russian/Chinese, for instance) texts/lists, while for English/Russian texts/lists we want to use one byte per symbol encodings like KOI8-R or CP1251.
