sample ODT document using Unicode 10c80:10cff

Attached is an Writer document prepared on Windows 8.1 Ent with
Version: 5.3.2.2 (x64)
Build ID: 6cd4f1ef626f15116896b1d8e1398b56da0d0ee1
CPU Threads: 8; OS Version: Windows 6.29; UI Render: GL; Layout Engine: new; 
Locale: en-US (en_US); Calc: group 

Cleared the language defaults.

The default style Western font is set to the sample "Unicode_Maros_ext" at 12
pt with no language. The default style CTL font is also set to
"Unicode_Maros_ext" but at 40 pt, and the language set to Hungarian
(Szekely-Hungarian Rovas).

With glyphs for codepoints used in a "Western" paragraph, the layout/shaping is
not RTL.  But if forced to be CTL with RTL paragraph, they codepoints are
layout/shaped as RTL.

If it were correct, shouldn't strings coded with the glyphs from 10c80:10cff
always be RTL direction even when mixed into a Western class text? Presumably
for example Hungarian (with Latin derived fonts) mixed with Hungarian strings
using Rovás font.  Doesn't seem we can do that.
