@databases/validate-unicode

The @databases/validate-unicode package validates and strips out invalid byte sequences from unicode strings in JavaScript. This is important because JavaScript does not enforce that strings with multi-byte characters are valid, but many other systems can crash or behave in unexpected ways when encountering these strings.
