Subscript and superscript buggy when naming a power symbol

When trying to name a (power) symbol "+24V_{Unreg.}" Kicad automatically corrects the name to "+24V_{brace}Unreg.}". Thus instead "+24V_Unreg._", "+24V_brace_Unreg." is displayed (italic text is meant to mark subscript).

Since I have a project that has both regulated +24V as well as unregulated +24V I want to create a power label with the name "+24V_Unreg._". The naming problem should however be relevant for all symbols, not only power symbols, since when I create a new symbol and type in a name that contains either subscript or superscript something like "^{superscript}" is changed to "^{brace}superscript}". Upon changing the name again, the text is corrected to "^{brace}brace}superscript}".
