The bug is not related to the is_printable vector at all. All output
to terminal and log is not done according to the is_printable vector,
but according to the isprint() function.
isprint() is a standard library function of the locale subsystem, not
related to TeX's is_printable vector at all.
The is_printable vector is considered for \write to filedescriptors <= 16.
And, yes, if the tcx file has
<input_code> <tex_internal_code>
then the tcx code in web2c sets
is_printable[<tex_internal_code>] := 1;
So, to sum it up:
1) \writes to filedesc <= 16: printability check done against the
is_printable vector. This has been ok (only problem: documentation
is not explicit about this)
2) \writes to filedesc > 16: have been checked with isprint(), but
the argument of the check was not the character that would be output.
This was wrong, and my fix has fixed this.
