Hello,
I just finished an update to the exception library I am planning to propose for addition to Boost. I appreciate all feedback, including incompatibility reports with various compilers (I believe the implementation to be standard-conforming, but I have only tested with msvc 7.1/8.0 and gcc 3.4.4).

I am not a exception expert, but I am just wondering, why the exception library does not support UNICODE. Is there any technical restriction?
If a exception library support UNICODE as , we can throw user friendly message.
I think this is the wrong way to go, especially in a multi-lingual world. You should throw an error code (and some additional) information, and create an error message to display to the user at a higher level. This means that your low-level code (which could be throwing the exception) doesn't need to know the details of displaying the error message (in an alert on the screen, or written to a log file, or sent to a pager, or ?) nor the language in which the error message will be displayed in (English, German, Italian, Uzbeki, ?? ). [ Note that this is not a rejection of Unicode, but rather a separation of the error being detected and thrown and the creation of an error message ] Just my 2p. -- -- Marshall Marshall Clow Idio Software <mailto:marshall@idio.com> It is by caffeine alone I set my mind in motion.
