Under Linux xkeyboard-config 2.22 have Old-Hungarian keyboard layout as extra layout
Comment 5 Julien Nabet 2018-03-09 10:29:38 UTC
Could you give a try to 5.4.5 or the brand new 6.0.2 ?

You can find recent LO version on LO ppa (see https://launchpad.net/~libreoffice/+archive/ubuntu/ppa)

Thank you for your feedback, since I don't have more questions, I'll put it back to UNCONFIRMED.

Mark: thought you might be interested in this one.

Old Hungarian (runic) writing is not RTL or LTR, it is unidirectional, and there were vertical uses as well. (And it's possibly not Hungarian either, but that's for another day.) 
Just consider this when forcing a direction.

I don't know what your problem about it. Since earlier years of 20th century accepted as RTL script. Before that times, existed LTR or vertical form, but widely used as RTL. That true, this script used by Székelys, but their spoken language is Hungarian, Hungarian translated name Old-Hungarian keyboard layout is "Székely-magyar rovás". Please don't reopen this bug-report because of your theoritical problem.

I am sorry, I was little bit nervous. I set back it to UNCONFIRMED, because I had thought before it fixed.

Apology accepted. 

My problem is that this writing system is a target of nationalism, lot of nationalist bias and misinformation (about the writing style and usage details of the script). Some sources of information (mainly about real technicalities, like the direction of the writing; but many of them about claimed use cases) are unreliable or strongly biased. A few years back I have tried to gather info on the topic from lot of "idependent" (=not politically motivated) sources and the result were that the writing system were used differently and by different people as it has been claimed by some Hungarian "authority on the subject". One case was specifically the directionality which I gathered was not restricted to one direction and plenty of archeological findings showed LTR, RTL or vertical use. (The historical ambiguities and its related politically motivated background is really not interesting from our point of view; LO shall support the writing systems which really exist and all of their possible uses; while we cannot quite establish that it existed in the wild after the 17th century it's definitely used by lots of people in the 20th and 21th century, for various reasons. I think the level of support should be the same as other ancient scripts not in everyday use anymore.)

All in all: it is used in both directions by scholars and people enthusiastic about this historical script, recent uses prefer RTL.

It is RTL as encoded for the block by its acceptance by Unicode as Old Hungarian (10c80-10cff)--that is the only development standard we are bound to.

So a Unicode compliant RTL--is the only handling LO will implement using standard ICU BiDi library handling for the language block.

From the LibreOffice projects perspective it is a RTL, Complex Text Language. And folks choosing to place glyphs from the code block LTR must override the applied ICU BiDi defaults.

Closing this as dupe of 116322 which is the more general case of string entries in Calc not observing ICU BiDi control for Strong RTL script by code block.
