The obverse Greek inscription: ΒΑΣΙΛΕΩΣ ΣΩΤΗΡΟΣ ΜΕΝΑΝΔΡΟΥ (Basileos Soteros Menandrou; of King Menander, the Savior)
The reverse Kharosthi inscription: 𐨨𐨂𐨱𐨪𐨗𐨯 𐨟𐨟𐨪𐨯 𐨨𐨅𐨣𐨪𐨯
The reverse inscription usually appears in coin catalogs as Maharajasa tratarasa Menamdrasa; “The Savior King Menander”. The Kharosthi might appear in a table at the end. It's real text here. (You may need a font to see it.) You can cut and paste it to other documents.
One of my hobbies is trying to put coin inscriptions into computer format. Hopefully I came close. Step one was glancing at the Unicode Kharoṣṭhī proposal, especially the table at the end.
This is what I came up with:
Ma-e-na-d-ra-sa 𐨨𐨅𐨣𐨪𐨯 (using a zero-width space to help position; using ra instead of the compound dr)
