Regarding Fraktur, beside any revivalist activities, it has a continuous
use for special purposes. For instance, it is used on labels of
"traditional" foods, on restaurants and store signs, and on menus of
some "traditional" restaurants. It is also sometimes used for
typesetting, especially when preserving the appearance of "classical"
German literature of the 18/19th century.
However, the problem of MS Word et al. and ligatures is deeper, beyond
Fraktur. Almost any quality Latin typesetting uses at least fi and fl
ligatures, and the adequate OpenType liga instructions therefore are
contained in widespread fonts like DejaVu or Linux Libertine, as well
as in high-quality fonts like Adobe Minion Pro.
If a software like MS Word does not support this, you simply cannot do
quality typesetting in Latin with such a software.
At least, the current beta of MS Word 2010 supports ligatures in
principle. The fact that this does not work with a lot of fonts
containing OpenType liga or rlig tables (like the Breitkopf Fraktur
included in my previous mail, beside others) may be a problem of the
Beta version (I hope some Microsoft employees who read here will file
it as a Beta case, as I did not figure out until now how to give Beta
feedback to MS by appropriate effort).
Also, MS Word 2010 Beta has only one stage of ligature enabling, not
distinguishing (to name only the base OpenType features affecting
rlig: required ligatures, like Arabic lam-alif, which only may be
turned of for test or similar purposes, as the text appears "wrong"
when turned off.
liga: ligatures, like Latin fi/fl ligatures. These should be "on" by
default, as the text appears "unpleasant" when turned off, ignoring
the concepts which the type face designer had in mind when creating
the type design.
dlig: discretionary ligatures, like Latin st resembling U+FB06.
Such, of course, should be "off" by default.
This results in at least three "ligating" levels:
"Test": None on
"Normal": rlig + liga on
"Prettified": rlig + liga + dlig on
("rlig on only" does not seem to be necessary).

This in fact addresses a special rule of Fraktur. It is true that only
the ligatures "ch", "ck", and "tz" are not separated when letterspacing
(German: "Sperrsatz") is used (the common way to emphasize text in Fraktur,
as italics is inapplicable and boldface uncommon there), while the
other ligatures are separated by spaces. However, this rule has no
influence how letter pairs are treated if there is no space between
them. However, the fi/fl/Å¿i/... ligatures are "required": In printed
material from the 19th century, in Fraktur they are used without exception
(beyond the explicit rule that they are forbidden on boundaries within
compound words, to be marked with ZWNJ in plain text).
Letterspacing is something which ideally would be treated on a higher
protocol level, like italics. But while there seems to be no HTML
tag pair comparable to <i> ... </i>, in text software it can be
simulated by specifying a positive intraword character distance.
To indicate to such a software which ligatures it has to separate
then, it seems appropriate to declare the ch/ck/tz ligatures as
"rlig" and the other ones as "liga".
I have modified the "Breitkopf Fraktur Uni" in this way (see
attachment), and the simulated letterspacing works fine this way with
Adobe Indesign CS4 (see attached specimen).
