Question

I’m developing an application for a native language learning. I need to store some characters as ‘ẽũ’. My database is set to utf-8 charset with a default collation, also the table affected by this characters.

The problem is when I try to add a row using a regular SQL insert:

INSERT INTO text(spanish,guarani) VALUES('text','ẽũ');

This throws a warning:

Warning Code : 1366 Incorrect string value: '\xE1\xBA\xBD\xC5\xA9' for column 'guarani' at row 1

And the result is “??” where there are those characters.

Question: These characters are not covered by the UTF-8 charset? Which one I need?

Note: Same problem with latin-1

Thanks.

QUICK!!! Read http://www.joelonsoftware.com/articles/Unicode.html

It is required reading.

Once you have read that, you should ask yourself:

1. What encoding is the connection using.
2. What locale is collation using. (If applicable).
3. What encoding is the SQL statement in?
4. What encoding are the string literals in?
5. What encoding is the html form presented in?
