HDF5.jl with vector of tuples of strings

Specific Domains Data

@mkitti I just stumbled on another similar string related issue. If one tries to write a Vector{@NamedTuple...} where at least one type is a string, the writing fails.
This is on v0.17.3.

using HDF5

arr = [
       (;A="A",B=1),
       (;A="A",B=2)
       ]
 h5write("test.h5", "test", arr)

ERROR: ArgumentError: Could not convert non-bitstype @NamedTuple{A::String, B::Int64} to @NamedTuple{A::HDF5.FixedString{1, 0}, B::Int64} for writing to HDF5. Consider implementing convert(::Type{@NamedTuple{A::HDF5.FixedString{1, 0}, B::Int64}}, ::@NamedTuple{A::String, B::Int64})

The funny thing if that these arrays are actually the output of h5read…
I can open an issue on github if you prefer, but this felt pretty related to the OP.

Please create an issue. It is difficult to track these things here.
