export result

Hello !
I want to export to excel 2007 use XSSF, but i found some string can't export correctly such as "IBM_x3550_M2", this string will be export to "IBM㕐M2".

Then i found the problem is "_x3550_", when the string's format like "_xNUMBER_"  and the NUMBER is a Unicode code , then it will be export to "_xChinese character_".

Is this a bug of XSSF ?
Or there are some other ways to resolve it?

PS:Use HSSF to export Excel 2003 is correctly!

Could you include a code sample to reproduce this?

I was hoping for a code sample that is less than 20 lines. I do not understand what function is causing the problem from comment 0.

What code is called when you "export to Excel"? Where is the Unicode string set? Is this on an existing document or a new document? A concise code sample should be able to answer this.

code sample like this :

XSSFRow row = sheet.createRow(rowNum);
XSSFCell cell = row.createCell(i);


XSSFRichTextString richString = new XSSFRichTextString(textValue);

We had a few discussions around this already, see https://bz.apache.org/bugzilla/buglist.cgi?f0=OP&f1=OP&f3=CP&f4=CP&j2=OR&list_id=151221&product=POI&query_format=advanced&short_desc=_x&short_desc_type=allwordssubstr for some matches. 

Specifically bug 57008 discussed this. Short answer: this is how Excel encodes special characters and the POI API currently does not interfere with these escape-sequences currently, so to solve this you should escape strings like these as described in bug 57008, specifically "This seems to be an Excel "feature" and if you prepend this string with "_0x005F" the string stays at it is."
