Are there any plans to get UTF-8 support in OpenMotif? I have a small patch, that adds UTF-8 to the XmFONTLIST, but I think this might be not enough.
The patch is applies to the latest OpenMotif 2.2.3 beta release (2004-03-04).

UTF8
In fact, UTF 8 support requires considerable effort. It isnt just the case that you plonk Xutf8* routines into the XmString rendition code, and add Xutf8 font metric code into the XmFontList handling methods. You have to be thorough, and also make sure that ICCCM 2.0 specification updates for UTF* are handled in all aspects of inter-client communication, drag/drop, selections, and so forth. Basically, wherever TEXT components are transferable, you also have to be prepared to export/import in UTF8. This means that the convert/destination XmTransfer codes all need an update also.
And make sure that Motif supports the UTF8 ICCCM 2.0 Window Manager properties.
Technically, not difficult at all. The issue is one of rigorous application throughout the toolkit. And associated utilities.
This is mandatory for any Motif 2.3.
