Line break (\n) not working in ios when escaped via StringEscapeUtils.escapeJava

Question

I am using compile 'org.apache.commons:commons-lang3:3.4' library to convert emoji from my android app so that it can easily decoded in ios. So in my android app to encode string into unicode i am using this method StringEscapeUtils.escapeJava its working fine emoji sent via android app showing in ios but when i sent data which contains some line break, in ios it shows \n instead of showing text in new line.I tried

        val actualText=editText.text.toString()
        val oldText=StringEscapeUtils.escapeJava(actualText).toString()
        val newText=oldText.replace("\n", "\r\n")

but its not working.

Answer 1

After struggling a lot i found the issue. for these statements:

        val actualText=editText.text.toString()
        val oldText=StringEscapeUtils.escapeJava(actualText).toString()
        val newText=oldText.replace("\n", "\r\n")

This picture(output) will clear everything

after using StringEscapeUtils.escapeJava for old text \n not considered as escape sequence character. So i changed replacement statement to:

val reviewText=oldText.replace(StringEscapeUtils.escapeJava("\n"), "\r\n")

and then output is:

after this in ios app instead of showing \n it shows text to the new line.
