To make the point more clear, the female golfing Unicode “character” is encoded as follows in various UTFs: UTF16 (12 bytes total): \ud83c\udfcc\ufe0f\u200d\u2640\ufe0f UTF32 (20 bytes total): u+0001f3ccu+0000fe0fu+0000200du+00002640u+0000f

Yeah, I’ve not seen anything that I love there unfortunately. Ton for the former, but not much for the later. I’ve thought of trying to create it, but I know how hard it is to produce great content and how unrewarding it is.

> Porting that from ASCII to UTF-32 is just dividing the length in bytes by 4. For UTF-8, you'd have to iterate over each character and figure out if there is a combination of bytes that collapse into a single character. You have to

Why use Bluetooth at all? Depending on the details, hiding a wire inside a sleeve should be doable. If you really want wireless, I’d suggest considering something like RFM69 / RFM95 type radios. You can easily find a wide variety of fo
