The explicit use the length marks is not approved by Unicode, they are used
only for the rendering purpose. The data entered should use the authentic 'ai'
matra character only. 
This is a bug with the data on the given website. 

The reason Pothana tends to give right output is that, it does not have a glyph
for U+25cc, i.e. the dotted circle which is used to notify the invalid
syllable, such as a vowel sign without a consonant. The obvious disadvantage of
not having dotted circle is that, it may allow users to type in wrong sequences
without notifying.

So, from both the rendering and font point of view, its not a bug.

For getting the right and authentic output with universally valid data, please
use the 'AI' Matra character U+0c48, and drop the use if the length mark
U+0c56. The problem should be reported back to the website, if possible.

>From Pothana's point of view, it should include a glyph for U+25cc at right
position to avoid confusion and use of invalid sequences. As I can see, it has
the glyph, but not at right position. As pothana is still in packaging process
for fedora, the problem can be reported only upstream.
