Transcoding vowel-marker characters

[funderburkjim]

In #76, @Andhrabharati proposes an extension to slp1 for representation of vowel-marker characters of Devanagari. Let's continue that discussion here.

[funderburkjim]

In deva->slp1, how do we know when to insert the marker?
Also, how to type examples? I use pramukhime to type Devanagari.

Does opening the new issue and 'continuing the discussion' mean that the point has been accepted in principle?
[otherwise, no point spending time on this!]

[funderburkjim]

point has been accepted in principle?

Not sure how to answer. Since the need for such an extension is rare in the current CDSL,
this issue is not pressing. However, I am curious to see whether the cdsl transcoding
scheme can be extended in the way suggested.

[Andhrabharati]

This may be somewhat comparable with the jihvAmUlIya and upadhmAnIya characters that are rarely come across!!

a first test

Work appears in issue78 directory.

There is no problem in extending slp1_deva1.xml to display the vowel-marker characters.
Compare test01_in.txt and test01_out.txt.

deva1_slp1.xml was extended in the most obvious way. Applying this to test01_out.txt yields
test01_in_out.txt, which is different from test01_in.txt.
Thus, invertibility fails for this version of deva1_slp1.xml

Recall that a transcoding file specifies a finite-state machine, which processes a text string.
The deva1_slp1.xml state machine has only one state (named INIT).

Thus, it's finite state machine does not distinguish the context of, for instance, \u093e (Devanagari Vowel Sign A); so it always generates the slp1 'A'.

Note that slp1_deva1.xml takes 2 states to generate Devanagari from slp1.
Perhaps a version of deva1_slp1.xml with 2 states could properly distinguish the context.

The deva1_slp1.xml state machine has only one state (named INIT).

Too abstract for me. For long time something I totally do not understand ))
