I'm using i18next to handle translations in a project I'm working on and I'm finding that when I hand a string to the translation that contains /, it is being converted to the unicode hex code /

I am setting title as:

const title = '2/Double/Twin/Triple/Quadrupple'

The translation is called as follows:

{i18n.t('foo', {
  title,
  amount: '$18'
})}

And the translation is setup like:

{
  "foo": "foo bar {{title}} howdee {{amount}}"
}

However the output is:

Foo bar 2/Double/Twin/Triple/Quadrupple howdee $18

How do I ensure that characters are not converted to their hex code equivalents?

By default i18next escapes content to avoid xss attacks based on user input. You can turn off escaping by prepending - or provide escape flag.

{
  "foo": "foo bar {{- title}} howdee {{amount}}"
}

or

{i18n.t('foo', {
  title,
  amount: '$18',
  interpolation: { escapeValue: false }
})}
