shaperglo hi_Deva will always fail as it will produce dotted circle

[mitradranirban]

As my font failed I checked with NotoSansDevanagari-Regular

shaperglot check NotoSansDevanagari-Regular.ttf hi_Deva
Font does not fully support language 'hi_Deva'
 * FAIL: Shaper produced a dotted circle when shaping shaping the text 'अ ॄ ॐ ई ग ऑ ऐ श ब द ए ढ थ फ ऌ ण छ औ ळ ॉ ओ न भ ऽ ॅ आ ऍ ड ख व ञ इ ट ध ऊ च क त स ङ य प ठ ह झ म घ उ ज ल ऋ ष र'

As the test is placing stand alone vowel marks and considering a dotted circle as fail, all Devanagari font will fail the test. Please ensure marks and vowel marks are not place standalone

Thanks; this is an issue with the underlying language database, which I will fix.

The language data is now fixed; the issue here with shaperglot is that, as you say, it is shaping a mark with a dotted circle then complaining that a dotted circle was produced. That is fixed in the Rust implementation but not in the Python yet.
