Table directive can not deal with Chinese, when format csv

[[!table  format=csv data="""
a,b,c
1,2,你好
"""
]]

But the below example works well.

[[!table  format=csv data="""
a,b,c
1,2,3
"""
]]

The below example works well too

[[!table  format=dsv delimiter=, data="""
a,b,c
1,2,你好
"""
]]

You don't say what actually happens when you try this, but I hit something similar trying unicode symbols in a CSV-based table. (I wasn't aware of the DSV work-around. Thanks!) The specific error I get trying is

[\[!table Error: Cannot decode string with wide characters at /usr/lib/x86_64-linux-gnu/perl/5.24/Encode.pm line 243.]]

That file is owned by the libperl5 package, but I think I've seen an error mentioning Text::CSV i.e. libtext-csv-perl when I've encountered this before. -- Jon

A related problem, also fixed by using DSV, is messing up the encoding of non-ASCII, non-wide characters, e.g. £ (workaround was to use £ instead) -- Jon

Sorry, I have faced the same error: [[!table Error: Cannot decode string with wide characters at /usr/lib/x86_64-linux-gnu/perl/5.24/Encode.pm line 243.]] -- ?tumashu1

The below patch seem to deal with this problem:

Thanks, I've applied that patch and added test coverage. done --smcv

I can confirm that the above patch fixes the issue for me. Thanks! I'm not an ikiwiki committer, but I would encourage them to consider the above. Whilst I'm at it, I would be really grateful for some input on support multi-row table headers which relates to the same plugin. Jon
