FAQ
About Computer Utilities.
Are Unicode and emoji counted correctly?
Yes. Every counter iterates via code points (spread iterator), so combining characters and multi-code-point emoji contribute one visible character, and UTF-8 byte lengths are computed with the standard TextEncoder.
Which typing-speed formula do you use?
The industry-standard convention: 1 word = 5 characters. Gross WPM = (chars / 5) / minutes; Net WPM subtracts uncorrected errors per minute; accuracy = (chars − errors) / chars × 100%.
Do the encoders enforce integer input?
Yes. The Hex/Binary converter accepts decimal integers, `0x…` hex literals, and pure binary strings; anything else raises a clear validation error rather than producing NaN.
Is anything sent to a server?
No. Every calculator runs entirely in your browser — no accounts, no uploads, no logging.
