Empty translation results in sourceText using qsTranslate

pacqfc

I'm using qm for translation. If a translation value is intentionally empty, qsTranslate treats it as invalid translation and returns the sourceText.

For instance, if I have this in the ts file:

<message>
   <source>note_txt.value</source>
   <translation></translation>
</message>

qsTranslate(context, 'note_txt.value') returns 'note_txt.value' instead of ''.

Is there a way to specify an empty translation string?
