Max,

File a bug report in the PROJ.4 bugzilla with the issue, the correct encoding
as well as a bit of supporting information (such as test points).  I can then
add it as an override or possible if I understand the pattern I will be able
to modify the epsg translation script (and GDAL/OGR, etc) to handle this
properly throughout.

I must admit I stopped following this thread in detail.  Is there a general
lesson on how a particular EPSG projection method code should be rendered
into PROJ.4 format that I should be taking away from this?

Best regards,
