Well, JSesh doesn't handle latin text in columns very well (but, on the other hand, good handling would require significant extensions to the Manuel, as, for instance, rotated text. This being said, there is something which is definitly a bug and not a lack of feature:
If you enter the following,
+l1.+s-iwn_-n:t-!+l2.+s-G5*G7_-N31_-t*Z1_-xAst-!+l1.+s-iwn_-n:t-!+l2.+s-G5*G7_-N31_-t*Z1_-xAst-!
+l1.+s-iwn_-n:t-!+l2.+s-G5*G7_-N31_-t*Z1_-xAst-!
and display it as columns, each column will be shifted slightly downward from the previous one. Which is not nice.
(Bug solved in development version 2.11. will be corrected in the next JSesh release. Also added margins for texts in columns).
Insert a very small space at the start of each column. You may use ".\1" (half-space scaled 1%).
Note that .\0 (half-space, with scale 0) doesn't work here.
.\1-+l1.+s-iwn_-n:t-!.\1-+l2.+s-G5*G7_-N31_-t*Z1_-xAst-!
