I found that if I pass any interpolation options without including escapeValue, this.escapeValue will get set to undefined in Interpolator. The documentation indicates escapeValue defaults to true, so this could cause variables to not be escaped as expected in some cases.

This config, for example, will result in i18next not escaping variables as expected:

  interpolation: {
    prefix: "__",
    suffix: "__"

It's worth noting that it could potentially be a XSS security issue for users of i18next if they believe variables are getting escaped when they actually aren't.

BTW, for bonus points, I added a bunch of tests around the Interpolator options.
