concerns: first page to the first two pages , the first two pages of the first page of the information received in Chinese are garbled

split into two pages , too, as above.
project UTF-8 encoding
JavaWeb started learning phase , the next chapter stresses javabean
------ Solution -------------------------- ------------------
pageEncoding page information is encoded , while setCharactrEncoding is encoded parameters between pages .
------ Solution ---------------------------------------- ----
pageEncoding settings argument does not work . Different browsers sends the information to the server using a different encoding , indexed to set request.setCharacterEncoding.
------ Solution ---------------------------------------- ----
page data sent is the character , you need to specify the character set
------ Solution --------------------- -----------------------
pageEncoding equivalent to just page encoding format, and setCharacterEncoding refers argument encoding
----- - Solution --------------------------------------------
Floor already said
------ Solution ------------------------------------ --------
in response to another page when it is coupled with UTF-8 encoding , and sometimes not with gb2312 utf8 can solve distortion ,
------ Solution --------------------------------------------
request.setCharacterEncoding ("UTF-8"); setting the request object passed parameters.
String voteName = request.getParameter ("voteName");
String voteType = request.getParameter ("voteType");
int voteOptionNum = Integer.parseInt (request.getParameter ("voteOptionNum")); these few lines to get parameters from the request . Set the encoding type will not be garbled
------ Solution ------------------------------- -------------
pageEncoding and request.setCharactrEncoding
------ Solution ------------------- -------------------------
request.setCharacterEncoding ("UTF-8"); setting the request object passed parameters.
then write data to be received there will be garbled
------ For reference only --------------------- ------------------
request.setCharacterEncoding ("UTF-8");
can be displayed properly , but do not understand why pageEncoding = "UTF-8" can not afford to effect ?
in other words, the request object data storage format is not UTF-8?
------ For reference only -------------------------------------- -
page data sent is the character , you need to specify the character set
pageEncoding page information is encoded , while setCharactrEncoding is encoded parameters between pages .
Thank you, understand, equivalent character stream
