Generatore di Ethereum Payment codice QR: errori comuni e come risolverli
Le modalità di guasto che accadono davvero, come appaiono nell’output e la correzione concreta.
Come si usa
- Controlla prima la codifica dell’input: un BOM estraneo o un incolla non-UTF-8 corrompe il risultato prima ancora che lo strumento venga eseguito.
- Cerca troncamenti silenziosi: se la lunghezza dell’output è sospettamente tonda, qualcosa è stato tagliato.
- Conferma che l’opzione modificata sia quella richiesta; un valore predefinito dimenticato è la causa più comune di un risultato plausibile ma errato.
- Riesegui con un input minimo verificabile a mano, poi reinserisci i tuoi dati reali.
