Re: [Wrapper-user] Lost logs after null character output on linux

[Christian M. <chr...@ta...>]

Hi,

thank you very much for your report. I will take a look into this.

However a very simple workaround would be refraining from null characters
in a String. If you know the String might contain a null character, maybe
you could try replacing the null character like this:

new String(byteArray).replace('\0', ' ')
So this way all occurrences of a null character in the String is getting
replaced with a space character instead.

Best Regards,
