Done

However any unic-xxx.tex have this line, and I try to make the same thing.

unic-001.tex has
\ifcase\numexpr(#1+1)\or
  \Amacron       \or
So if #1 = 000 then we jump to \Amacron and this is ok.

In unic-037.tex
\ifcase\numexpr #1\relax %
   \unicodeLightHorizontal\or
   \unicodeHeavyHorizontal\or
with #1=001
I jump  to   \unicodeLightHorizontal  first (and this is wrong)
and then to    \unicodeHeavyHorizontal (and this is ok)

With
\ifcase\numexpr #1+1\relax %
   \unicodeLightHorizontal\or
   \unicodeHeavyHorizontal\or
with #1=001
I jump  \unicodeHeavyHorizontal (and this is ok)
