Ⅳ. 文档说明

# vim-troll-stopper

Beware, there are (Unicode) trolls out there! Here, take this plugin for
protection.

Problem

There are many Unicode characters that are identical or look very
similar to one another. Best known example: semicolon (;) and a greek question
mark (;).

Trollers (e.g. your coworkers) can exploit this by replacing semicolons with
greek question marks in your code (original idea: Peter Ritchie, @peterritchie).
There are even tools that help you with
this and take it to the next level.

Also, any random code snippet from the internet/stackoverlow can be corrupt.

Demo, a cannonical "hello troll" program:

ⅰnt ⅿain() { рrintf ("Ηello troll!\n"); }

Copy-paste the above code to hello.c file and run $ make hello. Part of the
output:

hello.c:1:1: error: unknown type name 'ⅰnt'
ⅰnt ⅿain() { рrintf ("Ηello troll!\n"); }
^

Maybe you'd even start crying if you didn't know the above code is deceitful.

Solution

Vim users should know better than falling for these petty tricks.
This plugin highlights troll characters with a red background so you are alerted
something is not right.

After you install this plugin, things should just work for any and all
filetypes.

Installation

Just use your favorite vim plugin manager.

Features

• change highlight to custom color (in .vimrc)

  highlight TrollStopper ctermbg = red guibg = #FF0000

• use the :TrollStop command to convert invalid characters to regular ones
