    how to handle personal names, ontologies

    matial: not good for me after summer time comes in

    <aphillip> mati: -1, prefer same wall time rather than same utc

    <aphillip> richard: 1500 utc

    richard: prefer same wall time

    <fsasaki> +1

    <fsasaki> actually, both fine by me

    aphillip: resolved to move to 1500

    <aphillip> ... for first meeting in april

    aphillip: move to 1500 not next week but the following week

caseless matching in css3 fonts



    aphillip: c+s may not match

    <aphillip> example: a font with a german name such as heiƟ
    wouldn't match HEISS because C+S case fold is only "heis"

    aphillip: the concern is that you want your case-folded names
    to match the other token, and both have to be case-folded the
    same way...

    you have to know that you have to allocate a little more
    storage for the case-folded version...

    <fantasai> fantasai: Is the concern that the casefld will be
    incorrectly implemented, or that it won't match when correctly

    a little spurios, since other factors can change the length

    JcK; worrying about this particular case "borders on the

    <fantasai> Norbert quoting Jonathan: should require
    normalization if doing casefold

    <fantasai> ?: Trying to do casefold without normalization is
    all sorts of trouble.

    <fantasai> JcK: Maybe right rule is to normalize and casefold
    for comparison, even if the string is not normalized itself

    JcK: maybe the right rule is to normalize around case folds

    <fantasai> ?: A little more complicated, but certainly more

    <fantasai> aphillip: Would be remarkable use of normalization
    simply because not used anywhere else

    <fantasai> JcK: Should either not casefold at all or normalize
    and casefold

    <fantasai> aphillip: Don't think we want to change
    recommendation of which casefold to use

    <fantasai> aphillip: Second quesiton is whether to normalize

    <fantasai> aphillip: efficiency more problematic for
    normalization than casefolding

    <fantasai> aphillip: We've brought it up with Selectors, other
    things, een told enough times we're not going to get

    fantasai: in all other cases, you had to have normalization
    span the entire platform
    ... not sure that this can even been done
    ... in this particular case, it's not about interaction of css
    with some other Web technology but about interaction of CSS
    with font files via intermediary agent of OS font APIs

    you could require normaliza and case fold, and it would have no
    effect on the rest of platform

    <fsasaki> scribe: fsasaki

    addison: conclusions?
    ... need to understand the rules for common font format
    ... there seem to be limitations

    fantasai: normalization and case folding makes most sense to me
    ... in this particular case

    addison: nothing against including normalization
    ... objections against case folding should go away too

    jck: thinking of the argument for normalization we had for IDN
    ... These strings are very short, I don't see an efficiency

    addison: so probably both normalization and case folding are
    the right thing to do
    ... there should be a special note saying here is the limited
    case where we are having normalization

    <JcK> In particular, these are comparisons for very short
    strings, not operations on very large blocks of text. For such
    short strings, The efficiency loss is trivial and the
    comparisons will work much more predictably

    <aphillip> ACTION: addison: write back to CSS-fonts about
    casefolding and normalization, allowing both with health
    warning (see minutes) [recorded in

    <trackbot> Created ACTION-198 - Write back to CSS-fonts about
    casefolding and normalization, allowing both with health
    warning (see minutes) [on Addison Phillips - due 2013-03-28].

css3-text-decoration skipping spaces



    addison: this is about space skip, text decoration for
    ... above link is summary of what I got back from them
    ... one of discussion topics: some langauges don't use spaces
    ... so if you want to (scribe missed)

    fantasai: reading comment esp. from markus
    ... propose to do something simple
    ... do something for languages that have spaces
    ... if the language has no spaces, you don't want to create a
    ... one thing I didn't understand: how do I specifiy other than
    linking to CLDR query page?

    addison: defined elsewhere, like the regex one

    fantasai: does the regex include entire Z category?

    norbert: javascript has its own ws category

    <aphillip> ACTION: addison: seek clarification on
    [:Whitespace:] [recorded in

    <trackbot> Created ACTION-199 - Seek clarification on
    [:Whitespace:] [on Addison Phillips - due 2013-03-28].

    fantasai: proposal is to skip all characters in unicode
    category z

    addison: minus the vertical white space

    fantasai: the word separater characters are:

    <fantasai> space (U+0020), the no-break space (U+00A0), the
    Ethiopic word space (U+1361), the Aegean word separators
    (U+10100,U+10101), the Ugaritic word divider (U+1039F), and the
    Phoenician Word Separator (U+1091F)

    <fantasai> plus whatever is regex White_Space

    fantasai: that is the current proposal
    ... we can skip e.g. over blank
    ... do we also skip over visible spaces like U+1361?

    richard: skipping over blank might be an issue too

    addison: there are joining items in punctuation you might not
    want to skip either

    norbert: e.g. within numbers

    <aphillip> foo<a0>:

    <aphillip> 1<a0>000

    discussion on underlining in Ethopian word spaces

    <Norbert> [20]http://www.unicode.org/reports/tr44/#White_Space

      [20] http://www.unicode.org/reports/tr44/#White_Space

    <r12a> fantasai, do you know that you just dropped off the

    <fantasai> "conference is restricted" :/

    <matial> me too

    <fantasai> So any conclusions on text-decoration-skip?

    <fantasai> The definition I have is the one above

    <aphillip> I will circle back to unicore

    <fantasai> the open question is what to do with the visible
    word separators

    <aphillip> and we will take up again next week

    <fantasai> ok

    <aphillip> yep

language ranges with multiple subtags

    <aphillip> norbert: looking for end-to-end language negotiation
    example that uses script codes

    <aphillip> ... or other subtags defined by bcp 47

    <aphillip> richard we have some


      [21] http://www.w3.org/International/getting-started/characters

    <r12a> look at the chinese version

    <aphillip> norbert: please send examples to list

    <aphillip> richard: see above
