I wrote an impact analysis on UTF-8 in the RIPE database last year: https://labs.ripe.net/author/ed_shryane/impact-analysis-for-utf-8-in-the-ripe-database/ We already support UTF-8 in the Whois REST API and on the website, but convert to/from latin-1 in the database. Switching to UTF-8 in the database is not technically difficult, but we need functional requirements from the community on where to allow UTF-8 characters. This proposal is only to support more Latin-1 characters to be supported in names, while preserving backwards compatibility for querying (by also doing normalisation to ASCII). > Have the effects of LATIN-1 on downstream applications such as NRTM v3 > and NRTM v4 been considered? Allowing Latin-1 in these name attributes *does* impact NRTMv3 and NRTMv4 (as they will no longer be ASCII only), but these characters are already allowed elsewhere in RPSL (e.g. the workaround of putting the correct name in the "descr:" attribute). Also the object primary key will remain ASCII. > > You indicate that LATIN-1 already is supported in the RIPE database, so > I imagine you and the team already deliberated on the pro's and con's of > UTF-8 vs LATIN-1; and as such concluded with this particular > recommendation.
