Performance and resolution issues

[c121914yu]

Test Url: https://zh.minecraft.wiki/w/Minecraft_Wiki:%E5%BF%AB%E9%80%9F%E5%8F%82%E8%80%83%E9%A1%B5

When I try to parse this url, it takes about 20 seconds in the node environment. It seems to be parsing out some characters that aren't there, and I haven't figured out why yet.
