Bug #13216: Possible unexpected behaviour reading string starting with a byte order mark
https://bugs.ruby-lang.org/issues/13216
* Author: Gabriel Giordano
* Status: Open
* Priority: Normal

* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
Maybe the comparison between symbols has an unexpected behaviour. Tested with ruby 2.4.0
