Follow these instructions after the test page opens.
The number of conjuncts supported by a font may be different from another font, so set the font to a specific value.
Identify the clusters that are presented by the font using a conjunct (ie. with a hidden virama) – these are the ones we are testing. (You can highlight some or all of these by clicking on them.)
From the pulldown labelled "Run a test" choose "First-letter".
Check the results.
Test passes if no conjuncts are only partially selected (coloured blue) and enlarged.
