Special characters and units - Mailing list pgsql-general

Hi all,

I'm running PHP and PostgreSQL on a webserver to present data on the www.

I got a dataset that consists of measured values, each with a different
unit (micro, kilo,).

1. Where is the best place to store the units? In the identifier of each
column?

2. Some units are "micro gramms". Is there a way to store the special
character 'micro' (ASCII 181 / HEX B5) in the database or do I have to
use 10E-6 instead?

Thanks for any suggestions.

Regards,
Stefan Stern
