Conversion from code pages to unicode

Is there any support for conversion string in a specific code page to unicode in Gemstone/S.

Is it right, that Gemstone/S assumed ISO8859-1 for single-byte strings ? But this will not cover W1252 based strings.

I know, that the low-level libraries Gemstone used support this feature, but it is not available in Smalltalk.

Any ideas ?

Marten,

I think your best bet would be to look at GRCodec classes and implement your own encoder ... If you do take this route, it would make sense to publish your Codec in the Grease project for others to use.

I would rather like to use the embedded ICU libraries of your product ....

Could you submit an HR to get instructions for doing so? I assume that it is possible, but I am not familiar with the ins and outs of hooking up to the external icu libraries ...

Answer myself:

System gemEnvironmentVariable: 'GEMSTONE'

Sorry ...

$GEMSTONE should always point to the root of the product installation:

  System gemEnvironmentVariable: 'GEMSTONE'

should do the trick.
