Spaces in Poetry

[adaml]

I am publishing a poetry book using ePub reflowable 3.0 format. Some of the poems have extra spacing between words to position them uniquely relative to other words, for visual effect.

I am using multiple   entities to force spaces, which is working in other readers that I have tested it with (Adobe Digital Editions, Aquile Reader, Calibre eBook Viewer). However, Freda ignores the extra spaces and only renders one space between all words.

Is this by design, or do I need to use a different entity (such as nbsp) to make this work?

Thanks
