#63 Line wrapping breaks unicode characters

[Timo Weber]

If "Wrap long lines" is active (eg. after 100 chararcters) some unicode strings are broken after saving.
For example:
form.error.field.text = \u03A0\u03B1\u03C1\u03BF\u03C5\u03C3\u03B9\u03AC\u03C3\u03C4\u03B7\u03BA\u03B1\u03BD \u03C4\u03B1
will become
form.error.field.text = 3B1\u03BD \u03C4\u03B1
after activating line wrapping and saving.
