Keno - take a look at what I did in <a href="https:&#x2F;&#x2F;github.com&#x2F;ScottPJones&#x2F;StringUtils.jl" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ScottPJones&#x2F;StringUtils.jl</a> (building on the backs of giants, such as Tom Breloff, Dahua Lin, and others, incorporating some code from Formatting.jl).  It solves problems I&#x27;ve had both with string literals, formatting, and outputting funny Unicode characters (without having to use UTF-8 in my source code).<p>I really like your Cxx.jl, that does seem to answer the issue raised here (are there any good features in pybind11 though that aren&#x27;t already in Cxx.jl? that might be a good source for ideas on how to improve Cxx.jl if not)
