That is the missing piece of code.
Our resolver API already uses Unicode strings and is, thus, ready to accept
domains in any language. Summarising a quick check I've done of the KDE
- - QStrings (thus, Unicode) are used almost everywhere when hostnames are being
regarded. So there should be no loss of information when moving that data
around in applications and libraries
- - The current resolver API (of which I'm the author) uses has QStrings in
input and output values.
- - The current resolver code doesn't know how to handle IDN domains, so it just
transforms the Unicode into a 8-bit representation and sends to the lower
level functions. It is here that the new encoding/decoding functions have to
- - Most problems arise when related to legacy code (i.e., before this API was
introduced), C code and other stuff outside the KDE libraries (DCOP, KDE-ICE,
Arts, krfb) and the encoding of special characters done in URLs. These
problems have to be quickly dealt with.
I should also mention that the resolver API is currently being rewritten and
IDNs have always been considered. I had even planned of adding an
encode/decode function to translate a Unicode-based hostname into its 8-bit
(or, in this case, 7-bit) format, which would be a placeholder for the future

I believe I would be that person in KDE.
