Subject RE: Unicode Characters in Input Fields
Date Wed, 08 Jan 2014 17:44:52 GMT
Alex,

Few notes:

1.Regular Expression [^\x00-\x1F\x7F]  can be used as "not" to  allow characters in the range
0-31 and 127 i believe. Not clear of \177 in the below mentioned reg ex.

2. Also, i believe when we say unicode, we mean only extended ascii charcter set( excluding
non printable range 0-31,127), but not complete unicode code points?  I believe this will
as well effect  mysql db and other code areas in CS of storing and handling these values changes.
Changing  encoding either to utf-8\other for that column and byte set to read and write to
accommodate the range we are looking to handle?


Thanks!
Santhosh

Alex, is there a bug for this in JIRA ?

If yes, you can submit a patch via review board and describe the tests you did to make sure
this does not break anything .
