An Air Carrier pilot reported that signage on Taxiway C does not identify Taxiway B while taxiing in either direction.

Narrative

The CHS airport taxiway signs at the Taxiway B and Taxiway C intersection are inadequate and/or missing. While moving southwest on Taxiway C toward Taxiway B; the only sign depicting the Taxiway B turn is placed past the Taxiway C/Taxiway B intersection. This placement past the intersection is nonstandard. The Taxiway B turn sign should be placed before the Taxiway C/Taxiway B intersection for standardization. While moving north on the ramp from the gates toward Taxiway B; there are no signs identifying Taxiway B. There should be a sign that identifies Taxiway B as the jet approaches Taxiway B from the ramp. I am not sure if Taxiway A is identified with a sign or not. We did not take that route out of the ramp area. While moving north on Taxiway B (unidentified taxiway) toward Taxiway C there is no Taxiway C turn sign (either direction). However; there is a good sign at the Taxiway B and Taxiway C intersection; which has an arrow pointing left toward Runway 3 and an arrow pointing right toward Runway 33. While moving northeast on Taxiway C toward Taxiway B; there are no signs identifying Taxiway B. There should be a Taxiway B turn sign along Taxiway C (northeast) located before the Taxiway B turn. Thanks for looking into the CHS taxi signs.
