Although Old Turkic is not short
of available scripts developed to write it,
only the Runic script was particularly designed
to adequately reflect many unique grammatical rules of Old Turkic.
For instance, none of the other languages
whose scripts were adapted to write Old Uygur
were particularly agglutinative nor do they use vowel harmony
or require consonants to be either leaders or followers,
depending on whether they are 'stops' or not.
The wiki on the 'Turkish Alphabet' says,
“Whereas Arabic is rich in consonants
but poor in vowels,
Turkish is exactly the opposite.
“The script was thus inadequate
at representing Turkish phonemes.
“Some could be expressed using four different Arabic signs;
others could not be expressed at all.”
On the other hand it appears
that Voynichese-Manichaean-Old Turkic
may have developed specific recognitions
of all of these features into its structure.
We will soon see.
