+For IE 11, you'll also need a polyfill to support unicode regex patterns. For example,
+
+```js
+const rewritePattern = require('regexpu-core');
+const {generateRegexpuOptions} = require('@babel/helper-create-regexp-features-plugin/lib/util');
+
+const {RegExp} = global;
+try {
+ new RegExp('a', 'u');
+} catch (err) {
+ global.RegExp = function(pattern, flags) {
+ if (flags && flags.includes('u')) {
+ return new RegExp(rewritePattern(pattern, flags, generateRegexpuOptions({flags, pattern})));
+ }
+ return new RegExp(pattern, flags);
+ };
+ global.RegExp.prototype = RegExp;
+}
+```

## Browserify
ExcelJS publishes two browserified bundles inside the dist/ folder:
