Still getting the same error. please click on the below link for verification
balel.js try it online where I pasted your escaped version of this, but babili minification still minifying without quotes for identifier...When I paste it in IE-11 browser console, I get Invalid character error.

@kumkanillam I see. Not sure what to do on my side to make this work. I think that you have to report the error in babili itself, or one of it's plugins.

@cibernox Thank you quick the response. After the minification escaped versions is replaced by the non-utf8 chars. so issue still exists.. IE browser shows error link(https://docs.microsoft.com/en-us/scripting/javascript/misc/invalid-character-javascript) which has invalid character rule, but I am not sure which char is causing this error

My point is that if the code before minification works, and after minification it doesn't, it's a bug in babili itself. My best advice is report the bug in babili. I suspect that the transform that breaks the code is actually this one: https://github.com/babel/babili/tree/master/packages/babel-plugin-transform-member-expression-literals

Closed as this is a bug in babili, not in EPS.
