[MapProxy] Unicode support in layer names?

[Rahkonen Jukka (MML)]

Hi Anders,

Oliver was referring to source name in MapProxy configuration.  In your old mail you told you are using

layers:
  - name: Other-objects
    title: Other objects
    sources: ['wms_trans:Øvrige_objekter']

Oliver was suggesting to use simple name 'wms_trans' for source and define the layer name of the remote server inside source definition

Did you try this?

Layer name in WMS service can be any string. However, in other OGC services rules are more strict (Feature type names in WFS and coverage identifiers in WCS 2.x). If you ever configure your own server, use only names that are good as NCName http://stackoverflow.com/questions/1631396/what-is-an-xsncname-type-and-when-should-it-be-used. You can always use titles and abstracts for humans and reserve names for computers.

Hi Oliver

Apologies for not responding sooner.
When you say source names are required to be basic strings (I interpret it as English characters only), is this a limitation in Mapproxy or in the WMS specification itself? Do you perhaps know where in the specification this is specified?

When specifying the layer in the source part, I get the following traceback in the log:
