I have recognized the same issue with the attached swf:

1. Select / copy Chinese text 巫石 in FlexPaper -> paste to notepad: failed 
(become 'ff')
2. Select / copy Chinese text 巫石 in PDF -> paste to FlexPaper search 
window: success
3. Search '巫石' in FlexPaper: success ('巫石' highlighted)
4. Search '巫' in FlexPaper: failed (no text highlighted)

After debugging the source code downloaded from the SVN site I find that:

1. TextMapUtil.checkUnicodeIntegrity() incorrectly recognized the Chinese 
characters as "invalid" text and convert these characters to "ff"

I have commented line 2276 of Viewer.as:

// _currentlySelectedText = 
TextMapUtil.checkUnicodeIntegrity(_currentlySelectedText,null,_libMC);

And how the Chinese text copying works fine.

2. For the failure to highlight the matched character when search text consists 
of only a single Chinese character:

It turns out that the drawCurrentSelection() of Viewer.as requires at least 2 
characters for the text highlighting to work properly.

==> Follow up question:

Is it possible to change the drawCurrentSelection() implementation so that text 
highlighting also works if only a single character is searched?

Your response is always highly appreciated!!!

Dear Erik,

Thanks so much for the fix!!

Is text highlighting for single character search supported in build 1.4.7 as 
well?

Dear Erik,

I have noticed that there is an attempt to fix issue #1 in stopSelecting() in 
line 2378-2379 as follows:

if(ResourceManager.getInstance().localeChain[0] != "zh_CN")
    _currentlySelectedText = TextMapUtil.checkUnicodeIntegrity(_currentlySelectedText,null,_libMC);

However, apart from simplified chinese (zh_CN), there are many other languages 
which use multibyte characters (e.g. zh_TW, zh_HK, jp, kr etc).

This languages will pass the "if" condition but 
TextMapUtil.checkUnicodeIntegrity() would not work for them.

Please find a better solution to cope with this situation as there are many 
Asian users who would be using FlexPaper, thank you!!
