Does LessTif support I18N?
Two widgets that accept text input (namely XmText and XmTextField) do support it, but they don’t feature multibyte support. This means you can use sequences such as Multi_key+c+o to get ©, Multi_key+n+~ to get the ñ, etc.. These work because they’re part of the ISO Latin 1 character set, which is based on one-byte representations. The XmText and XmTextField widgets can handle input methods, as described above, but they don’t have multibyte support. This means that Asian input methods which work with a multi-byte representation of a character will not work (yet). The XmIm*() API is work in progress, this is probably not a problem for you as we have yet to discover an application that uses it.
