वीरमित्रोदय: राजनीतिप्रकाश (महामहोपाध्याय मित्रमिश्र - प्राचीन भारतीय राजनीति एवं शासन कोष)

' in 'ध्व': that's 'ध' + 'व'.
Look at line 1: "देवीपुराणोक्तेन्द्रध्वजो..." -> 'ध्व'.
What does 'द्व' look like in this font?
Look at line 7: "दैवज्ञः".
Look at line 22: "तथा".
Look at line 12: "ध्वजार्थे वर्जयेद्त्स".
In line 21:
Is it 'द्व'?
Wait, look at the first part: वि - द्यु - द्
Then: 'व' ? 'ज्र' ?
Wait, look at 'ज्र':
In 'वज्र':
A 'ज' with a diagonal stroke '्र' is 'ज्र'!
Does the character before 'ह' look like 'ज्र'?
Look at 'ज' in line 21: "परिवर्जयेत्" -> 'र्ज'.
Look at 'ज' in line 18: "यवनजां" -> 'ज'.
In line 21, the character has:
a left-facing curve, a middle horizontal, a vertical line, and a diagonal slash to the bottom-left!
THAT IS A 'ज्र' (jra) with a ra-phala!
Look at it carefully:
It has the three prongs of 'ज', a vertical stem, and a slanted leg going down-left: 'ज्र'!
Wait, and what is above it? An anusvara?
