Michael: icudata contains, among other things all the supported utf16<->other-codepage convertion. If your locale is utf8 or iso8859-1/15 (which is most likely in your case) then sure you just need one or two of these conversion table... if any at all (some convertion like utf8<->utf16 are algorithmic) libicudata also contains stuff about collation and locales... There are ways to use your own, or to use a directory of individual ressources files ( http://userguide.icu-project.org/icudata ) . but then you'd have to ship the resource file in text form instead (which might compress better) either way libicudata is big, but there is not that much redundancy in it. it just covert and insanely large number of code page ( http://source.icu-project.org/repos/icu/icu/trunk/source/data/mappings/convrtrs.txt ) and locales. if you start stripping stuff out, you will reduce the functionality for people using more 'exotic' locale (which where they live may not be exotic at all :-) ) Norbert (Note: The above is based on memory of work I did 6-7 years ago on icu... things may have changed since version 2.4 :-) ) > > b48de000 13588K 84K 84K 0K 0K > r--p /data/opt/OOInstall/basis3.3/program/libicudata.so.40.1 > > Which makes it rather a good target for dropping from the pagein-common > map I suspect; just commit that fix; but it'd be great to shrink our > install and download size by having a dig at exactly what is and is not > used in libicudata; perhaps an easy hack to add ? > > HTH, > > Michael. > > -- > michael.me...@novell.com <><, Pseudo Engineer, itinerant idiot > > > _______________________________________________ > LibreOffice mailing list > LibreOffice@lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/libreoffice > _______________________________________________ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
