This character (U+0445), অ (U+0985), Յ (U+0545), օ (U+0585), ׅ (U+05C5), अ (U+0905), Ӆ (U+04C5), and ԅ (U+0505), all possibly among others, all trigger this error. I was attempting to use the second (which generated this error), and seeing that both অ's and х's UTF-8

Clarification: labels, descriptions and aliases are all affected. Editing a description already containing this letter (i.e. not '''adding''' this letter but just '''keeping''' a letter added before) is not possible either.TASK
