You are presuming that all fonts contain name strings for glyphs. TrueType
fonts with a format 3.0 post table do not. Of course, anyone hoping to take
advantage of a system such as you propose would likely not use that format,
but it is a mistake to assume the presence of glyph names in a font.
More importantly, what you are proposing -- especially as interpreted by
William Overington, below -- is a hack that goes against the driving
principles of Unicode text processing and smart font technologies like

That name would be interpreted by Adobe's Acrobat glyph->character parser
as a ligature of 'g' and some unknown entity called 'ct'. If you're going
to give meaningful name to glyphs, I recommend you first learn the
conventions that are in use by current software.
But what do you achieve by using Pim's technique to insert your 'golden'
(really fatuous name, by the way) ligatures into text? -- even supposing
that any browser developer were inclined to implement such a technique,
which they will not be. You render text unsearchable and unsortable; you
make it impossible to copy and paste text from the page into another
document in which you might want to set it in another font. Effectively,
you've killed a document in the interests of making it look pretty.
There are technologies that implement the Unicode Standard in a sensible
way, that employ smart font technologies to format text in a sophisticated
way without destroying the underlying text strings. Yes, it is true that
current browsers only widely support such technologies for complex script
rendering, but do you really think that browser makers are not going to
continue to develop the technologies to which they are already committed,
to achieve the kind of goals that you are interested in? Just because
something has not been implemented on your computer doesn't mean it has not
already been solved by software developers. We have a model that works for
rich typography on top of Unicode text processing: it works in my page
layout applications, it works in my image editing software, it will
eventually work in my web browser.
