Answer 1

Lack of Bidirectional and Glyph Shaping support is a known restriction of the FireMonkey platform, on all targets (including Windows and Mac OSX).

We will have to wait for "native controls" for Android as third party components for FireMonkey, as it does exists for iOS - see http://www.tmssoftware.com/site/tmsicl.asp for instance.

I've found this great blog article with source code about Android Native controls for Lazarus/FreePascal which is quite interesting. But this won't work with the "NextGen" Delphi compiler, which is currently going in a diverse direction in respect to FPC (e.g. with the ObjectivePascal mode).

Since it uses native Android controls, it should not suffer from the same restrictions as FireMonkey do.

Answer 3

As per LURD's suggestions.
Download and use D.P.F Delphi Android Native Components and/or D.P.F Delphi iOS Native Components.
That will fix the problem in XE7 and prior.
According to the documentation with the Delphi XE8 beta the problem is fixed there as well.

As a last resort (if you feel up to it), someone has taken the effort to patch the XE5 source code to enable BiDi support. See: https://docs.google.com/file/d/0BwumWe43CaijVDRQZzNQbXNSLWc/edit?usp=sharing
