Defect Number

Enhancement Number

Cause

Resolution

Progress 9.x and earlier:
These releases do not support any form of Unicode interactive client.
Progress 9.x does support the Unicode (GUI and Character) batch client started with -b.

OpenEdge 10.0A and later:
These releases support the 4GL GUI Unicode client on Windows.
To start a Windows Unicode OpenEdge client specify -cpinternal with a value of UTF-8. For example:

prowin32.exe -p _ab.r -cpinternal UTF-8 -cpcoll basic

Any non-interactive client (batch-mode client started with -b, AppServer & WebSpeed agents) supports Unicode.

An interactive Unicode Character (not GUI) Client is not supported. There are currently no plans to implement this.
