Obviously, but the character "é" can be represented by the single Unicode
codepoint U+00E9 (aka LATIN SMALL LETTER E WITH ACUTE) or by the sequence
U+0065 U+0301 (aka, LATIN SMALL LETTER E, COMBINING ACU

The "n" represents _a number_

It's confusing because the "n" represents a buffer size. Even allocating
four bytes you cannot store 1 "character" because a chara

The language spec is a bit confusing with respect to the what the "n"
actually means in CHAR(n). My copy says

You said your data was UTF8 (4-byte characters) and your connection
charset is NONE (which means US ASCII, one-byte characters). ASCII
"D" is stored as "44", while UTF8 "D" is
YES! Changing the column's type to VARCHAR(1) works.
Now can someone tell me why? Doesn't my experience still indicate that there
is some sort of bug with columns of type CHAR(1)?
By the way, I renamed the column back to TYPE and it doesn't seem to cause
any problems.

Hi,
Can you declare it as a VARCHAR(1)? Or try "select cast(recipt_type as
varchar(1)) from "

Here's a bit more info: I just walked through the execution of "SELECT
RECEIPT_TYPE FROM RECEIPT WHERE ..." in the debugger, and what happens is
that it is still selecting 4 characters, e.g. "D ", when the column was
declared as CHAR(1) and the real value should be "D". Obviously it ends up

OK, I have renamed the column (from TYPE to RECEIPT_TYPE) and I'm still
getting the same error message when I do "select * from tablename":
"Failed to enable constraints. One or more rows contain values violating
non-null, unique or foreign-key constraints."
However, I can execute the same SQL
