Developers Note:
Warning: Change Text to path in editor!
This solution will make sure that most text can be converted to path.
If the words do not appear correctly from your initially converted SVG then resubmit it after changing all words/text to path in your SVG editor.
The below illustrates a map but could of course just as easily apply to a floor plan or anything so proceed to the next step.
Developers Note:
The above shows how the text from the uploaded SVG is ignored.
Follow the below illustrations from Inkscape to get them included.
