Hi Dennis, Dennis E. Hamilton schrieb: Hi! You are digging into my favorite subject. We talked about your interest, but with my small spare time, my progress is slow. I am assuming you are talking about strings within the MathML and that it is in some form of XML. In that case: If it is XML, the encoding can be specified in the ? ... ? XML prologue. Sniffing for this prologue will determine such things as whether UTF8 or UTF16, and big-endian or little-endian. If single-byte, that will usually mean some kind of code page which has a subset of ASCII as a common subset of a larger encoding, such as Western European. In that case, one can read the content of the prefix to see what it says, because it should be in a simple, pure ASCII form. Even if it is a double-byte character encoding, such as Shift-JIS, the prologue only needs the single-byte portions that are the same as ASCII. MathML is XML. But because formulas are seldom used as stand-alone files, when users e.g. copypaste a formula from a website, they get not a complete file but only a fragment. Such fragments can be used via Tools Import Formula in module Math. That had worked in OO1.1.5, (where users need to choose the filter themselves) and it works in LO, but currently fails in AOO. The default, however, depends on the MIME type of the XML file. Text/xml and application/xml have different defaults. Also, MIME types can have parameters that specify character sets. If no BOM and no encoding is given, UTF-8 can be assumed. (I would need to search for the correct reference for MathML 2, but see http://www.w3.org/TR/2009/WD-MathML3-20090604/chapter6.html#world-int-transf-flavors, last sentence.) The way Windows manages this also includes using a Unicode prefix on UTF8 (big-endian, I think). These are not uniformly used across platforms. Not even unique for MS applications. The Math Input Control produces UTF-16 and Word produces UTF-8. The parser can handle both. I have tested it already. Internally, because ODF and AOO are Unicode based, it is necessary to translate all arriving text into Unicode for internal storage and use by the application. To do otherwise, lies madness. There are difficulties with this, because Unicode allows local specializations. This comes up in craziness around Symbol fonts that do not have common Unicode correspondence. (Bullets in AOO have this disease.) There is no problem in this aspect. I only need to examine the input stream, whether it can be used with the smath-filter. I have probably provided more information than you require. I love this subject. Me too. I have not looked at your code. No need to spent your time on it now. I have attached it only to show what kind of methods I need. Kind regards Regina - Dennis PS: The default representation of XML inside OOXML is UTF16 as I recall.

RE: ruby uno to control openoffice
I think we have a misunderstanding somehow.
I need to take some time to reflect on what you have discovered and also look
at the codee.
I have pressure to complete some other commitments.
After April 15, I will dig deeper.
Thank you for your digging into this. It has been instructive.
Namaste,

Hi,Dennis
I replace openoffice 3.4.1 to openoffice4.1.1.
static const ::sal_Int16 OPTIONAL = (sal_Int16)256;//still I commented line
Runo can open a writer with no error .
There are may be errors later since i commented that line .But the main
problem seems is that the openoffice version
is not right.
I want to share my pleasure with you and the community.
Thanks for all the help.

Where the error occurred the first time, there are many lines the same.
See if you can find either declarations or #define statements for any of
those capitalized names that do not fail.
There may be clues there.

You are right.OPTIONAL was replaced by preprocessor.
cl /P yields module.i
OPTIONAL was disappeard in module.i
But i have not found where is #define OPTIONAL .
I will search again tomorrow.

Some place, there is a

That you want to work. It might be in an #include file. Ideally, it

You need to find all of the places in the code that uses that header
and
uses OPTIONAL and it is not in anything like #ifdef OPTIONAL but some
usage
where it is clear that a variable or expression form is expected in
regular

The clean fix is to change the name in both places. Most programs are
careful to do this in the first place, to avoid conflicts with other

of a similar term.
Because this is an .hdl, it may be more complicated than that. There
may
also be failures elsewhere that are undetected because they do not
