RTF character encoding

[vermaha]

I am working on a little tool that looks for certains strings / tags in RTF files. Now, those RTF files are not "regular" rtfs. These are actually FrameMaker MIF files that were exported to RTF for translation (in TRADOS). The RTFs are in fact bilingual.

This poses problems when I want to display text from these RTFs using PHP. I can find the strings I'm looking for with PHP's pregmatch function (based on some FrameMaker tags) but I cannot display the results - a sentence in Portuguese or Russian for example - appropriately on a web-page, since I have no clue about character encoding / conversion for those files.

• Example in RTF source:
  The English string "Settings and Adjustments" is translated into Portuguese as "Programa\'e7\'f5\loch\f0 es e ajustes".

• what you see in Word:
  "Programações e ajustes", where
  \'e7\'f5\loch\f0 = çõ

Does anyone know how to transform this into HTML entitities without using Word? Help much appreciated!
Thanks

Not sure if this will help - we use this technique to replace characters so that we can send it as valid XML double-byte characters to FOP.

function convert ($strData) {
	$arMap = array(
	   "/\\\\\\\[']e7\\\\\\\[']f5\\\\\\\loch\\\\\\\f0/i"	=> "çõ",
	   // all your perl regex mapping goes here
	);

$strResult = $strData;
@reset($arMap);
while (list($strFrom, $strTo) = @each($arMap))
{
	$strResult = preg_replace($strFrom, $strTo, $strResult);
}
return $strResult;
}

echo convert("Programa\\\\'e7\\\\'f5\\loch\\f0 es e ajustes");

Well, that's indeed the kind of thing I am looking for... but I am not going to spend time figuring out the sequences of each and every character for all common languages - if you see what I mean. We are not supposed to reinvent the wheel.

So where can I find (complete) libraries? What is this encoding called? Anyone?
Thanks
