r/Tulu

(Apologies for the invisible letters, if any, I am using a Tulu-Tigalari font, whose fallback font may have not yet been released on most devices.)

Excluding almost every letter, which shares its resemblance with the sister Malayalam script, these two letters seems to be foreign?

113B4 looks like flipped 𑎈 (11388, TULU-TIGALARI LETTER VOCALIC L) and also the Kannada equivalent ೞ (ZHA), but with a repha marker - just like र्म (RMA) in कर्म (KARMA)? If we go by the Kannada-specific voice, this sound is RZHA not RRA?

And where is 113B5 coming from? To me, it resembles a LA (Tulu-Tigalari - 𑎭, Kannada - ಲ, Malayalam - ല, Telugu - ల) but with another one of those loops just at the end. But the Unicode page mentions the sounds as LLLA, and as you can see below, every LLLA sound is ZHA.

From the Malayalam unicode:
> 0D34 ഴ MALAYALAM LETTER LLLA = zha

From the Tamil unicode:
> 0BB4 ழ TAMIL LETTER LLLA

From the Kannada unicode:
> 0CDE ೞ KANNADA LETTER FA
> ※ KANNADA LETTER LLLA
> • obsolete historic letter
> • name is a mistake for LLLA

Which between 𑎴(113B4, TULU-TIGALARI LETTER RRA) and 𑎵 (113B5, TULU-TIGALARI LETTER LLLA) is "ZHA"? Both of them? Or are there no "ZHA" at all?

Is the first one then RRA, just as mentioned, and LLLA a longer variant of the LLA?
