Extended Unix Code (EUC) character sets include several white space characters which have no ASCII equivalents. These characters are not recognized as white spaces by Portal Access. This may lead to incorrect handling of HTML pages, XML files and/or JavaScript files in these character sets.


Page or file in EUC encoding scheme may not be parsed correctly.


- HTML page, XML file or JavaScript file in any EUC encoding scheme (EUC-JP, for example).


Use an iRule to replace non-ASCII compatible white space characters by ordinal spaces.

Fix Information
