Description

When the definition I want to go has a \, it can't navigate there using symbols-view:go-to-declaration.

So when the tagfile looks like this:

< MyClass	test/class_one.rb	/^class MyClass # rubocop:disable Metrics\/ClassLength$/;"	c

It doesn't work, but when it looks like this:

> MyClass	test/class_one.rb	/^class MyClass$/;"	c

It does. Here you can find a more detailed explanation.

Steps to Reproduce

1. Have a class declaration (in this case in Ruby) that also has a comment with a / so it gets escaped:

class Foo # rubocop:disable Metrics/ClassLength
  def foo
    1
  end
end

2. Create another class that uses the first one, and generate a tagfile using universal ctags

class Bar
  def bar
    obj = Foo.new # <- go to declaration doesn't work for `Foo`
    obj.foo # <- go to declaration works for `foo`
  end
end

Expected behavior:

When stepping on Foo and trigering go-to-declaration, it should navigate to it's declaration

Actual behavior:

When stepping on Foo and trigering go-to-declaration, nothing happens

Reproduces how often:

Always
