No text, but a visual code

But I think it is a better approach than ciphre cracking

Definitely, this approach has potential. And it would solve many problems. A sequence like "daiin dain" would be expanded as "aui~ says and aii~ says". 
Common glyph order would be explained by syntax, i.e. word order in abbreviated phrases. And the lack of recurring phrases in Voynichese would be solved, since common phrases are reduced to "words". Suddenly d-aiin is the kind of phrase we are despreately looking for.
