It is a feature that makes a lot of sense, but only works within "modern" environments that can deal with Unicode. Most websites fulfill this requirement, but Mudcat is a charming relic from a different era. Our attempts to teleport it into the present time have failed. See all those threads about codepages etc.

Actme: as for InDesign, I just read "It was the first DTP application to support Unicode for text processing". My guess is that in its "Settings" or "Options" there is a little option list for "Codepage" - switch it to "Unicode".
