Possible JS/Java/C convertion problem

This is what I input into the JS/Java/C textbox (with C-style + \n etc options)
```
hi \\n there
```

On convert, the output in Characters become this:
```
hi \
 there
```

Shouldn't the output be `hi \n there`? Cause when we click convert again on the Characters part, the JS/Java/C textbox would be modified and become `hi \\\n there`, with an extra backslash.
