Sharing Biblical Hebrew Text Problem

It seems there are at least 7 different Keyboard "Schemes/Maps/Keyboards", etc.

Consequentially sometimes it seems impossible to communicate.

Sorry, I'm not really into Hebrew, but I try to clarify for mayself (possibly others as well) what you are aiming at. 

Is it transliterations? (some write checed, others hesed, others much different latin characters with or without diacritical marks to express a transliteration of the same Hebrew word - but this is way beyond the computer-relevant OS/application/font issues)

Or is it keyboard maps (you hit maybe CTRL-A to produce a Hebrew Aleph character, someone else may hit Shift-F7 to produce the same - which will be the case, but I don't see the immediate issue since an Aleph is an Aleph and looks like an Aleph regardless of which key you pressed to make it look so, or whether you simply inserted it with a copy/paste move or a tool like Logos' Shibboleth. Sharing the Hebrew text should not be an issue.)

Or is it fonts, so your Aleph looks like an Aleph, but your friend sends over a document which should contain an Aleph but you only see an A or a slash with a number behind it or something else idiosyncratic - and only if you would install and use a certain font, the Aleph looks like an Aleph again (if so: then the solution is for all of you to use Unicode fonts instead of outdated non-unicode fonts. And in this case there are some macros that may help. However, it still may be the case that actually typing those fonts on an English keyboard will require different keystrokes to come to the same character)

I'd start with what Mick recommended, as addressing that may resolve some other issues.

I'd think the important issue would be that everyone be able to read what someone else has written (which can be addressed by via using Unicode fonts which will be able to display the proper characters, regardless of operating system). Once you get to that point, it might not matter what keystroke someone had to use to generate a specific Hebrew character.

If your group still has issues after that with sharing Hebrew text, then those can be dealt with specifically, with the certainty that it is no longer a font issue.
