The issue is that strings aren't input ranges in betterC [1], 
due to autodecoding.


Normally you'd work around this using std.utf.byCodeUnit, but 
that's currently broken, because std.utf attempts to import 
core.exception.UnicodeException from druntime at module scope 
[2], causing any betterC program that imports std.utf to fail 
compilation.


So, for now, I think the best you can do is probably to 
copy-paste byCodeUnit into its own source file, and use that 
until std.utf is fixed.

Oh right, thanks!
Its the third time that autodecoding bite me in betterC and i 
always forgot of the possibility.

Any reason for not work with betterC or should i file the issue 
?
