Simple check for non-ASCII identifiers

CoffeeLint.coffee

read = (f) -> if fs.statSync(f).isFile() then fs.readFileSync f, 'utf8'
tokens = cs.tokens read _.last process.argv
ids = _.uniq (token[1] for token in tokens when token[0] is 'IDENTIFIER')
console.log 'Identifiers that contain non-ASCII characters:'
console.log (id for id in ids when id.match /[^\w]/)

test.coffee

faces = '⚀ ⚁ ⚂ ⚃ ⚄ ⚅'.split ' '
roll = Math.floor Math.random() * 6 + 1
console.log faces[roll]

[δ, π, ι] = [3.1428571429, 22/7, 1e-6]
console.log "π ≇ #{δ}" if π - ι < δ < π + ι
