Speaking with the translator they encouraged me to replace the
two-character ASCII sequence with the proper chevron characters.
Although when going to print they are replacing the characters with
curly braces, they like the idea of the chevrons better. The real
issue is that the double angle brackets are not the only time that '>'
and '<' appear in the text. When outputting the text to an XML output
format, should these characters not be encoded to XML entities?
Dealing with scripts developed for non-Latin languages we can't just
assume these characters won't appear in some arcane form

What if this were a case where the angle brackets were properly encoded as such?
