http://archive.hetq.am/arm/ is encoded in ARMSCII-8 but is declared as x-user-defined, which makes the site fail to render correctly out-of-the-box in any browser but makes the site readable in Chrome and IE if the user has installed an intentionally mis-encoded font called Arial AM. To make the archives readable without special trickery, the site should convert the old files from ARMSCII-8 to UTF-8 and change the declaration from x-user-defined to UTF-8. Alternatively, once bug 213517, the site could (font license permitting) add Arial AM as a @font-face font, which would make the site work visually cross-browser without users having to have the font installed. Conversion to UTF-8 would be a better solution, though, because unlike the font hack, it would make clipboard and search work.
http://archive.hetq.am/arm/ returns 404, but on http://hetq.am/arm/search/?q=archive (also on http://hetq.am/arm/news/) there is an archive calendar where you can search articles back to 2003. Example: http://hetq.am/arm/news/7078/ Older articles (if there were any) seem not to be available. All works fine and is declared and encoded as utf-8. I'd say this is FIXED.
