Your links show me the 03c code for lt. I need the E084 number to correct the Open Office output.
Here is a summary of my problem, it is a follow up of previous exchanges with Robert on that issue. You may check the messages on:
I used to write my documents with MsWord.  I then converted them into xml/html.  I also implemented the mathml.  It worked.
I am willing to use Open Office. However, the formulas that are inserted with a math editor or with Open Office are extracted with codes generated in the Unicode Private Area!
My xml or html would display the ? marks instead of the expected characters.
My transformation is meant to be automatic, I cannot review each formula in order to correct its code in the mathml.  This is why I need to transform the characters into a code that IE can display.
In order to do this, I need the real UTF-8 code as explained by Robert.
Robert gave me the number for the < sign, I tried the transfomation and I got the appropriate display with IE.  I need to do the same thing for other characters.
Hope this is clearer.  Could you please tell me about the real UTF-8 code?

The correct numbers for characters that have entity names are listed in
the mathml spec, eg 

it's hard to imagine why you'd need to eneter + by number rather than
just typing + but the number is the usual ascii number: hex 2B

None of the offical numbers are in the private use area though so if the
question is what numbers are being used by this application that is
using PUA codes, I don't know, you'd have to look to the documentation
of that product. If they are using the PUA codes from MathML 1, you want
the old version of the bycodes.html file from MathML 1, which is
