JSesh is a word processor, for ancient Egyptian hieroglyphic texts. It's used in many professional egyptological publications: the IFAO, the JARCE, and all kinds of books.
JSesh texts can be copied and pasted into other softwares (as MS/Word or Openoffice). It is also possible to create pictures in various graphical formats (jpeg, png, pdf, svg, emf, macpict, etc...)
It is is definitely allowed to use JSesh for publication. Mention of its use (in the same way one does mention fonts used in a book) would be nice, but is not an absolute requirement.
JSesh is free: you can download and use it at no cost, and give copies of it.
JSesh is opensource: its java code is freely available (under the CeCill license). For the user, it's definitely safer, as it means that, even if its present author was unable to work on it, other computer scientists might take on the development.
What’s new in version 7.3.1
Updated on Mar 21 2019
It's somehow a small bug fix for 7.2. It should be a bit more consistent regarding copy/paste size. The main feature, if you have difficulties with copy/paste and word using Windows, is that EMF copy/paste will be now marginless, which is better when mixing glyphs with texts.
Besides, the default embedded format for RTF graphics is now EMF. It might suffice to solve many problems.
