How do I split Tamil characters in a string? When I use preg_match_all('/./u', $str, $results) ,

The Mystery In exploring precisely which characters were permitted in Java identifiers, I have stumbled upon something so extremely curious that it seems nearly certain to be a bug. I’d expected to find that Java identifiers conformed to the requirement that they start with characters that have the Unicode property ID_Start and are followed by those with the property ID_Continue , with an exception granted for leading underscores and for dollar signs. That did not prove to be the case, and what I found is at extreme variance with that or any other idea of a normal identifier that I have heard of. Short Demo Consider the following demonstration proving that an ASCII ESC character (octal 033) is permitted in Java identifiers: $ perl -le 'print qq(public class escape { public static void main(String argv[]) { String var_\033 = "i am escape: \033"; System.out.println(var_\033); }})' > escape.java $ javac escape.java $ java escape | cat -v i am escape: ^[

I've inherited a MySQL database which contains a field named Description of type text and collation of latin1_swedish_ci . The problem with this field is it contains utf-8 data with some Unicode characters, e.g. character 733, etc. Sometimes this character also exists in the field represented as HTML encoded "&#733" as well. I'm trying to read the table and export the data to a CSV file and I need to represent this character as a double quote. Reading the HTML encoded character is easy enough. However, it appears that the actual Unicode character is converted to utf-8 before I can do anything with it resulting in a "?". How do I read in the Unicode character 733 (U+02DD), recognize it and convert it? Here's a simplified (not tested) version of the code. <? $testconn=odbc_connect ("TESTLIB", "......", "......"); $query="SELECT Description FROM TestTable"; $rsWeb=mysql_query($query)); $WebRow=mysq
