Each character should refer to a single-character atom rather than having these dot things to differentiate between each single-character atom.

NO EXCEPTIONS
[b][i][o][u]NO EXCEPTIONS[/u][/o][/i][/b]
{b.i.o.u NO EXCEPTIONS}
becomes
{biou NO EXCEPTIONS}

But, in the case of a multi-char atom like tt, spoiler, sub, sup, quote, or img, we should make use of the dot things.

A dot should be used to denote the start of a multi-character atom and optionally the end of the atom, e.g.

_{fioc user}
[sub]fioc user[/sub]
{sub fioc user}
becomes
{.sub fioc user}

and

^/b/
[i][sup][b]/b/[/b][/sup][/i]
{i.sup.b /b/}
becomes
{i.sup.b /b/}
