I'm trying to get C# tags to work and I'm not getting anything to work,
so I have to start from the beginning;)

I have Universal Ctags installed as u-ctags

```
$ u-ctags --version                                                             
Universal Ctags 6.1.0, Copyright (C) 2015-2023 Universal Ctags Team
Universal Ctags is derived from Exuberant Ctags.
Exuberant Ctags 5.8, Copyright (C) 1996-2009 Darren Hiebert

  Output version: 0.0
  Optional compiled features: +wildcards, +regex, +iconv, +option-directory, +xpath, +json, +interactive, +sandbox, +yaml, +packcc, +optscript, +pcre2
```

I have C# source files.

Program.cs

```
namespace Common.Services
{
  public class Tester
  {
    public static void Main()
    {
      IBar Bar = new Bar();
      Bar.Hukarz();
    }
  }
}
```

IBar.cs
```
using System;
using System.Collections.Generic;

namespace Common.Services
{
    interface IBar
    {
        public void Hukarz();
    }
}
```

Bar.cs
```
namespace Common.Services
{
  public class Bar : IBar
  {
    public void Hukarz()
    {
        System.Console.WriteLine("ehlo");
    }
  }
}
```

I create the tags file, as such

```
u-ctags -R
```

The tags file looks like this.

```
!_TAG_EXTRA_DESCRIPTION	anonymous	/Include tags for non-named objects like lambda/
!_TAG_EXTRA_DESCRIPTION	fileScope	/Include tags of file scope/
!_TAG_EXTRA_DESCRIPTION	pseudo	/Include pseudo tags/

```

If I now convert this to GNU Global, as such
```
gtags --gtagslabel=ctags -f tags
```

, which outputs:

```

The resulting three G* files don't contain any symbols.

Any pointers as to what's happening here?;)
