[m17n-lib:00378] Re: [Scim-devel] How to check surrounding text is supported or not?

Sorry for the late followup.

(2) surrounding text is not supported by the client.

In the case of (2), Thai input method have to fallback to
buffering method (i.e. keep typed characters in preedit area
to assure to commit only a valid character sequence).

I was wondering if m17n-lib could somehow handle the fallback to preedit rather than having to implement two sets of input logic in the input map (one for surrounding text and one for without). For example si-wijesekera.mim currently still assumes surrounding text and so doesn't work in KDE or XIM apps. But perhaps it is non-trivial to infer preedit from proceeding input?
