[chirp_users] - character no supporting in Name field anymore?

Just imported my Kenwood D72A radio to make some mods after downloading the CHIRP daily-20151225 build, chirp shows all my previously added channels with the - character in them, but if I touch any of them it coughs errors says the - is not a supported character?

Is that a change based on model? My Radio supports it and it makes the display of multiple repeater channels nice to visually separate.
