There are a few issues on polymer-cli, wich breaks javascript files, when babel/minify is used inside.

https://github.com/Polymer/polymer-cli/issues/633
https://github.com/Polymer/polymer-cli/issues/886
https://github.com/Polymer/polymer-cli/issues/701

i think it's a utf8 encoding issue, but i don't know if it's in polymer-cli or babel or babel-minify. maybe someone here can help out?

fix: property names minification - removal of quotes
be6cfdc 
+ t.valueToNode(<objectExpressionNode>) returns an object expression
node and again but with a few other effects - it removes the quotes from
property names for some unicode which is not supported in Safari and a
few other older browsers. So we bail here and let propertyLiterals
plugin handle the conversion of StringLiterals to Identifiers.
+ Fix #627
+ Fix #706

@boopathi can you look if this also works?

@boopathi Please reopen this!

I've now tried again. Issue still exists.

You can try. Download jquery.min.js from https://code.jquery.com/jquery-3.2.1.min.js and run babel-minfy on it.

Some of the \0 in the file will be replaced with Ascii NUL and break the script!

@boopathi you can keep this closed. I've created a new issue, since this has nothing to do with polymer cli

issue: #732
