I saw a thing recently where a unicode encoding trick was used in an oauth phishing scam -- using unicode characters, a scammer was able to make an oauth connector that looked like the real company but passed through the company's "if (oauthConnector.name.toLowercase().contains('our name')) { throw new DenyError();}" check.
Now, it's up for debate whether any (psuedo?) financial institution should offer full oauth access (at least without having a human review possible oauth connectors), but the point is, decorative hackernews submissions are the least malicious use of this trick.
Go to your browser's menu bar, click 'View', go to 'Character Encoding', and select 'Western (ISO-8859-1)'. Now it's just garbage characters. (It's not reversed, but at least it's not bold?)
The cat should have stayed in a box, if this gains too much popularity, HN will read like MySpace back in the days.
And top HN news will be: "A browser plugin that translates Unicode back to ASCII".
