If the connection character set is UTF8 (this needs to be specified
explicitly!) then it looks like the driver is misbehaving.

The call is



define('TSL_FB_CHARSET', 'UTF8');   //NB: no dash, not 'UTF-8'

The 'problem' is that a CHAR(1) in UTF8 is sent as 4 bytes. If the
character in question is a one-byte UTF8 character, then the remaining
three bytes are 0x20 (a space). A driver should truncate the string to
the declared number of characters, but doesn't do that here.

A potential workaround might be to use VARCHAR(1) instead.
