If memory serves right, I don't think Qalam has discussed this topic; of
course, I'm referring to scripts that do have letter "case". Although I'm
not passionately interested in typography*, it seems that, so far, there
is no widely-used monocase face or face family that doesn't look slightly
distracting or worse. The only one I can think of, by name, is Peignot,
and imho, it is not a success. *only quite interested :)

As well, among decently-educated people, I don't see much of a trend, if
any, toward a monocase script. Are such scripts essentially novelties, for
limited use (surely seems so!), or is there any serious intention of
designing an acceptable (or better) monocase face? Being only a
dilettante, I'm not aware of any designers such as Hermann Zapf having
created a monocase face.

Are there any serious reasons for designing a monocase face? (I'd say,
probably not.)

As to personal styles, there are countless adults who, when called upon to
do hand lettering, have their own simple set of glyphs that is mostly
monocase. There are several likely attributes in such character sets,
including very-probable Turkish dotted I's, perhaps embedded capital K's,
nearly-total absence of capital L's (I once saw a hand-lettered sign
advertising "MIIK", sans serif), etc. One wonders whether these poor souls
were overwhelmed, in elementary school, by the number of distinct glyph
forms in common usage; including numerals, and such variants as different
styles of small a's and g's, I once came up with a rough count of about 60
or so. (Does anyone have a better count?)

There's a trade name, or was, "Cobbies", usually rendered sans serif and
all caps as "COBBIES". IIrc, it's for women's shoes. I sometimes wonder
how many people misread it as "Cobbles"...

Here in Waltham, it appears that the ability of our school kids to do hand
lettering with good literacy has improved a lot, although I really don't
know.
