With pleasure.

If I avoid std.string.stripLeft and use std.algorithm.stripLeft(' 
') instead it works as expected:

void main ()
{
    import std.stdio;
    import std.utf;
    import std.algorithm;

    string [] src = [ " \xfc" ]; // blank + latin-1 encoded u 
umlaut
    auto result = src
       .map!(a => a.byCodeUnit)
       .map!(a => a.stripLeft(' '));
    result.writeln;
}
