[Framers] ISO character Entities

[cuc tu]

Hi All,

I'm saving structured XML files and am looking for how to define character entities for the degree ° and mu µ symbols. I noticed percent % comes out as a character entity (& percnt ; ) so I searched for that term and found a couple of files:

C:\Program Files (x86)\Adobe\AdobeFrameMaker12\Structure\xml\isoents\iso-num.ent (1 hit)
Line 32: <!ENTITY percnt "&#x0025;"> <!-- PERCENT SIGN -->
  C:\Program Files (x86)\Adobe\AdobeFrameMaker12\Structure\xml\isoents\isonum.rw (1 hit)
Line 52: entity "percnt" is fm char 0x0025;

Is this looking in the right direction? It seems I could just add a couple of lines to these files if I knew how to code it properly (°), (µ).

Thanks for any guidance.
