I think I looked at this when I laid it out:

So we put the ISO code at the end and ignore whitespace. But including a prefix sign as with `€1.234.567,89 EUR` would break it.

You also included localized formatting (the '.' and ',' ) in your example that'll likely break on parsing without special handling. For interchange, you'll want to avoid using localized formats, e.g. stick to the "C" locale or something specific or agreed to between the involved parties.
