database. The field must be some sort of blob, and when I connect to
the database thru ODBC in MS Access, the field type comes thru as OLE
Object, and Access cannot read the field (it usually crashes Access).
I can sorta pick out the data that I need (7.0, 28, 5TH PRINCIPAL MRD,
10.0 - and these occur in roughly the same place in every record
returned from the db), but I am...

Hello!
I have Oracle 10g using AL32UTF8 as internal charset.
I have a documents table where uploaded files (I'm using modplsql
web-gateway (release 8i)) are stored in a blob-column. I upload a
CSV-File to this table which is in ISO 8859-1 Charset.
I now need to convert this binary data (which is in fact all
character-data) into utf-8.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
