StringDocument() of the TextAnalysis package

Hi there!

Has anybody been using the StringDocument() function of the TextAnalysis package for unicode encoded language strings?
However, if I use StringDocument() with a readin (greek) string from a file with the read() function, everything works:

mydata = open("/Users/atantos/Desktop/test.txt") do file
read(file, String)
end

StringDocument(mydata) # works fine

Here is the code line with the error message:

StringDocument(“είμαι οκ”)
Error showing value of type StringDocument{String}:
ERROR: StringIndexError: invalid index [8], valid nearby indices [7]=>‘α’, [9]=>‘ι’

It looks like that’s occuring in the show method, i.e. when it’s trying to print a summary. I filed fix string indexing in `summary` by ericphanson · Pull Request #257 · JuliaText/TextAnalysis.jl · GitHub to try to help fix it.
