Yep, I hear you Henry,
I wanted to be sure you were aware of the differences. The concern that I have
is that when the UTF-8 is broken up that the display be something that is a bit
more understandable for the user. I was playing around with it recently in
trying to develop a web based solution, which is a lot easier because there is
no constraint of a fixed font size. Here is a video of what I ended up with
https://youtu.be/eN9H-rMk1No and the key verb in the process was this one that
breaks a list of point numbers into appropriate chunks to generate characters.
utf_vts_
3 : 0"1
if. y-:'' do. return. end.
try. ((utf@:((1<.#)}.]));~((3 u: ":)@: (7 u: a.{~ (1<.#) {. ]))) y
catch. try. ((utf@:((2<.#)}.]));~((3 u: ":)@: (7 u: a.{~ (2<.#) {. ]))) y
catch. try. ((utf@:((3<.#)}.]));~((3 u: ":)@: (7 u: a.{~ (3<.#) {. ]))) y
catch. ({. ; utf@}.) y
end.
end.
end.
)
Thanks for all of your work on this, handling the variable widths and uneven
box boundaries within your constraints seems quite a challenge. By the way, the
most recent version of the beta that I could download was 7 on the Darwin
platform, so I have not had a chance to try out the solution to the CJK
character widths.
Cheers, bob
