This page mentions a Chinese font named 明兰终, which is designed with Chinese characters sized 7×7 pixels:
"明兰终"，估计只有 7*7 字体估计是作者自已点出来的
详细说明在, http://bbs.themex.net/forumdisplay.php?f=87 字体可以百度到下载。 使用 fontBuild 工具虽然选择的字号都是一样的，但出来的字比 Hippopo 小一号
(Edit: The last sentence might refer to the fact that "8 pixels" in some cases refers to 7 pixels character size plus 1 pixel spacing between characters, and in other cases to a larger character size of 8 pixels, like the character size of the Hippopo font. Does that make sense?)
I found a file named
「明兰·终」.ttf here, but after logging in and trying to download it,
I'm getting an error message that I don't understand: "抱歉，本版塊下載附件 碎鑽-1，本操作後您的碎鑽將不足 0 個，無法下載。您可以點我進入了解《下載證書》勳章免碎鑽下載的方法。"
This page seems to indicate a connection between
明兰_Mono (post title
明兰MONO, below it says
XHei Mono=明兰_Mono and so on, post tag
明兰_mono.ttf from here doesn't contain bitmaps.
Are there some traces of the font "明兰终"?
