Other comments

The problem is in the file src/util/mask.ts, in the line:

const defaultDelimiters = /[-!$%^&*()_+|~=`{}[\]:";'<>?,./\\ ]/

which is used by the function unmaskText:

new RegExp(defaultDelimiters, 'g')

However, IE11 requires the new RegExp(pattern, flags) constructor to provide the pattern as a String, not a RegExp object. The solution is to set:

const defaultDelimiters = "[-!$%^&*()_+|~=`{}[\]:\";'<>?,./\\ ]"
