There is writed in FAQ "Take the word "anglo-American" or the Italian
word "vederLa". Once you uppercase, lowercase or titlecase these
strings, you can't recover the original just by performing the reverse
operation". Why so stupid?
All we need for the reversibility of the case conversion operations is
two control characters. The first (let it be {F}) indicates that
letter should not be changed by ToUpper, ToLower, ToTitlecase
functions. The second ({T}) indicates the letter for "titlecasing"
except the first in line one. For exsample:
the {T}man and the {T}planet {F}Earth
The {T}Man and the {T}Planet {F}Earth
THE {T}MAN AND THE {T}PLANET {F}EARTH
So my question is Why we have bidi-algorithm and RLE, LRO, PDF etc.,
have arabian shaping and ZWJ, ZWNJ etc., have casing and have NOTHING
for control it, why?
