[Jprogramming] passing unicode argument to dll

[Kairit Sirts]

I experimented a little and got the following result.

If I leave the argument in UTF8 format (this is the default format, when typing in some string from the keyboard, right?) then I will get domain error and variable pointing to memory address is 0

  syllabification 'nägin'
|domain error: memr
|   syllables=:zerocut>    memr aadress,0,128
   aadress
0

If I pass the argument in unicode format then dll will process the word, but eliminates the umlaut characters

syl =: syllabification ucp 'nägin'
   syl
┌──┬───┐
│n│gin│
└──┴───┘
   datatype each syl
┌───────┬───────┐
│literal│literal│
└───────┴───────┘

I have also another question regarding umlaut characters: when I write text into file for example 2500 characters then the file is saved in UTF format, but when for example 3000 characters then the file is saved in ANSI format. I can't see any sense in that behaviour.
