Brother lethal kamikaze: I know how Quran was revealed to Prophet (SAW) and how it got written, so there is nothing to discuss about it, hence I am leaving that issue to come to current topic.
Coming to symbol ‘786’, I feel you did not read my post or did not try to understand what I wrote. So, please read my post carefully and try to understand it, then you will have no ambiguity.
I wrote that spoken word (Sound) is the language that we use to communicate with each other. These spoken words can be written using any symbol that others could understand … but other can only understand symbols if they know the script or recognise the symbol used.
‘Bismillah-ur-Rahman-ur-Raheem’ is spoken words or sound in ‘Arabic language’ that has a meaning. Sound in Arabic ‘Bismillah-ur-Rahman-ur-Raheem’ can be translated into different languages and then it would sound differently. For instance … if we translate ‘Bismillah-ur-Rahman-ur-Raheem’ in English than it would sound ‘In the name of Allah, the Most Beneficent, the Most Merciful’ … and here, both sound would be different.
Anyhow, we are not even talking about translation. We are talking about sound ‘Bismillah-ur-Rahman-ur-Raheem’ written using different symbol.
When we use Arabic script to write sound ‘Bismillah-ur-Rahman-ur-Raheem’ then symbol would be 
Anyhow, same sound`:bism: can be written in Roman script and then symbol representing
would be ‘Bismillah-ur-Rahman-ur-Raheem’… that means, both
and ‘Bismillah-ur-Rahman-ur-Raheem’ would produce same sound by those who know/recognise the symbol.
Similarly same sound can be written in numerical code and then symbol representing
would look like ‘786’ … that means, both
and ‘786’ would produce same sound by those who know/recognise the symbol.
Thus, in whatever symbol a person write ‘Bismillah-ur-Rahman-ur-Raheem’, the sound when reading would be same … obviously, as long as the person reading know/recognise the symbol … and thus it does not matter what symbol is used to write ‘Bismillah-ur-Rahman-ur-Raheem’.
For instance, those who do not know Arabic script but know Roman script, they would not be able to read
but would be able to produce correct sound if
is written in Roman script or ‘Bismillah-ur-Rahman-ur-Raheem’.
On the other hand, those who do not know Arabic script and also do not know Roman script, but know numerical code (something most people could easily know/recognise), they would not be able to read (or could produce any sound) when they would see
or ‘Bismillah-ur-Rahman-ur-Raheem’ but would easily read (produce correct sound) if they would see ‘786’.
Hence, ‘786’ is a valid symbol (numerical code) that most people could learn and recognise for ‘Bismillah-ur-Rahman-ur-Raheem’ =
and there is nothing wrong in it.
As for you saying that ‘786’ is just a number and means nothing, then the statement you made also applies to any writing for those who do not know and cannot read something written. For instance
would mean nothing (would be a meaningless figure) for a person who do not know Arabic script … and only those who know/recognise Arabic script would be able to read it producing right sound. Anyhow, those who know/recognise symbol
they would be able to read it producing right sound. Similarly, those who know/recognise symbol ‘786’ would be able to read it producing right sound
