I have a dbf file that include the letter ñ (common in spanish). It is read adequately with ArchGDAL.jl, but not with Shapefile.jl which uses DBFTables.jl.

from dbftables.jl.

Yes that's expected currently, someone needs to implement what I suggested above.

Try a PR if you like.

A good approach would be to connect StringEncodings.jl to the dbf byte codes or "Language driver id" in the table here: http://www.dbase.com/Knowledgebase/INT/db7_file_fmt.htm

There is already a field for this in the header, we just don't use it

lang_id::UInt8

We limit to ascii on write, we can also fix that:

out = replace(rpad(x, len), !isascii => x -> '_' ^ textwidth(x))

Probably the reason its like this is there is no real spec for dbf, there are just implementations, and they differ:

I have no experience at all with DBFTables.jl, but I wil try to take a look and follow your suggestions.
