Useful for code that expects data of a certain length, but lowercases it in between checking and using.
const c = String.fromCodePoint(i)0x0D
const c_lower = c.toLowerCase()0x0D
if (c_lower.length != c.length){0x0D
log(i)0x0D
}const c = String.fromCodePoint(i)0x0D
const c_lower = c.toLowerCase()0x0D
if (c_lower.length != c.length){0x0D
alert(i)0x0D
}
