patchfoo uses "dig". (Patchbay used "Dig" in 2016-2017; before that it used "yup"; now it uses "Like"). I should change #patchfoo to make it more configurable and show the expressions.

Manyverse uses this code to convert some expressions to unicode:

const THUMBS_UP_UNICODE = '\ud83d\udc4d';
const DIG_UNICODE = '\u270c\ufe0f';
const HEART_UNICODE = '\u2764\ufe0f';

export function voteExpressionToReaction(expression: string) {
  if (expression === 'Like') return THUMBS_UP_UNICODE;
  if (expression === 'like') return THUMBS_UP_UNICODE;
  if (expression === 'Yup') return THUMBS_UP_UNICODE;
  if (expression === 'heart') return HEART_UNICODE;
  if (expression === 'dig') return DIG_UNICODE;

  return expression ?? THUMBS_UP_UNICODE;
}
