Special characters converted in wrong in Upper case ?

Question

Hello,
In material description , some characters such as µ when converted into upper case it will be 'M' in stead of 'µ' . This is in SAP ECC unicode . But it's ok in R/3.
So in this case, Is there any solution for this problem ?
Thanks

MAKT-MAKTG : For upper case characters , When our client search for values when pressing F4 in material , If there's material description that contain 'u03BC', It will be displayed as 'M' in the text . This will happen in ECC 6 not in R/3 ( in R/3 two texts are the same) .
The different behavior you're observing between what you call R/3 and ECC 6 is not due to the different releases, but based on the fact that one system is Unicode enabled and the other not. I suspect that you are most likely logging onto the system with a language that's linked to code page 1100 (in the non-Unicode release). Code page 1100 is similar to the Latin-1/ISO-8859-1 code page, which is designed to have most characters for western languages, but does not contain all Greek letters (SAP would most likely use code page 1700 if you set a greek locale).
Again, it may sound silly, but you have to distinguish between the symbol µ (Unicode code point U+00B5) and the lower case greek letter u03BC (U03BC). SAP code page 1100 contains only the symbol µ (U00B5), which represents the prefix micro as for example in 1µm = 1 micro meter = 0.000001m. Neither the greek lower case letter u03BC (U+03BC) nor it's corresponding upper case letter exists in code page 1100.
The Unicode standard defines the greek upper case letter u039C (U039C) as the upper case to use for both the symbol  µ (U00B5) and the lower case greek letter u03BC (U+03BC), see for example the Unicode mapping chart for Greek (so that's why you see a different behavior in ECC 6).
I'm not sure why, but for some reason SAP found it worthwhile mentioning that they actually also convert the symbol  µ (U00B5) to u039C (U039C), though that essentially just means following Unicode standard.
