Intl NumberFormat does not show the Bitcoin Symbol

Question

the Intl.NumberFormat does not show the bitcoin symbol.

CFORMAT_USD = new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'USD', minimumFractionDigits: 8 }); 
CFORMAT_BTC = new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'BTC', minimumFractionDigits: 8 }); 

console.log(CFORMAT_USD.format(1000));
// 1.000,00000000 $

console.log(CFORMAT_BTC.format(1000));  
// 1.000,00000000 BTC

My workaround at the moment

console.log(CFORMAT_BTC.format(1000).replace(/BTC/,'Ƀ'));
// 1.000,00000000 Ƀ

Is there maybe a better (clean) solution?

Answer 1

According to bitcoin.it (https://en.bitcoin.it/wiki/Bitcoin_symbol),

The ISO 4217 currency code for Bitcoin is XBT. However, at the moment it is an unofficial code according to the ISO 4217 standard.

So the correct code should be

Intl.NumberFormat('de-DE', { style: 'currency', currency: 'XBT' })
