Which FPC version is this likely to be released in?

On a quick review of the code, all seems good. Just one point: 
GetDataSize seems to acknowledge CP_UTF8 as the only multibyte character 
set. The Firebird character set GB18030 (Chinese characters) is 
multi-byte (see wikipedia) and has code page 54936. I believe PostgreSQL 
also supports it.
