One aspect this would not help with is with letter forms that do not
resemble their forms in the code charts. The code charts usually
broadly answer the question "What does this code represent?". They
don't answer the question, "What code points represent this glyph?".
Problems I've seen in Tai Tham are the use of U+1A57 TAI THAM
CONSONANT SIGN LA TANG LAI for the sequence <U+1A60 TAI THAM SIGN SAKOT,
U+1A43 TAI THAM LETTER LA> and of <U+1A6D TAI THAM VOWEL SIGN OY> for
<U+1A60, U+1A3F TAI THAM LETTER LOW YA>. The problem is that the
subscript forms for U+1A43 and U+1A3F are only documented in the
proposals. The subscript consonant signs probably add to the confusion
of anyone working from the code chart. The people making the errors
were far from ignorant of the script.
