Hello all,
before writing this message, I wrote about this in other mailing lists without
solving my problem.
Maybe some of you can help me.
I have problems with a DB in postgres, when i try to insert Chinese strings in
UTF-8 format.
If I insert the data using a C++ program I have empty squares, in this format:
��� (3 empty squares for each chinese ideogram as that is the length in UTF-8)
If the string contains chinese mixed with ASCII, the ASCII is OK but the
Chinese is broken:
漢語1-3漢語 --> ������1-3������
All the data is read from a binary file. It seems it's read correctly, but
something happens when the query is executed.
(If the text is in a different language that uses only 2 bytes for each letter,
I will see only 2 empty squares per character, ex. hebrew, but this is not good
anyway...)
Strange things:
1. if i insert the record doing a query from command line (putty), the chinese
text is OK. This problem is only when i insert by the C++ program.
2. I checked the C++ functions involved by creating unitary tests; if i run
some other tests (on another virtual machine) the text is not damaged.
These strange things are confusing me, but maybe they will be useful
informations for somebody who had the same problem.
The DB is set for UTF-8
Name | Owner | Encoding | Collate | Ctype | Access privileges
--------------+-------+----------+-------------+-------------+------------------
postgres | pgsql | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
MyDB | pgsql | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
template0 | pgsql | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
template1 | pgsql | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
Previously I also tried with:
Name | Owner | Encoding | Collate | Ctype | Access privileges
--------------+-------+----------+-------------+-------------+------------------
postgres | pgsql | UTF8 | C | C |
MyDB | pgsql | UTF8 | C | C |
...
But the problem was the same.
I know that you would like to see the code, but it's too long (anyway if you
want i can try to write some lines of code, like connection to Db and so on). I
don't know if there is some log create by postgres when inserting damaged data,
sould be useful.
For now, in order to save your time my question is: did anybody of you have the
same problem?
(and how did you solve it?)
Thanks,
Francesco
