[FEATURE] count graphemes instead of code units in text fields

[Veraellyunjie]

Pertinent to "Something about myself", "Prompts" and "Send a compliment"

grapheme and code unit as defined at https://stackoverflow.com/a/27331885

With measly size of text fields, I tried to save replacing words with emoji. Ha,
many popular emojis like 🚀 cost 2 characters/code units
flags like 🇬🇧 cost 4 (could use GB costing 2)
👨‍👩‍👧‍👦 (Family: Man, Woman, Girl, Boy) is a single grapheme costing 11 characters/code units. Word family costs 6. Losing 5 😛

Please count graphemes instead of code units
