I've reworked my font Radical and done the following
• Several improvements to spacing and kerning.
• Most of the glyphs revised.
• Global reshape of inktraps.
• Font name change, from Radical Display to Novecento.
• Opentype Locl feature added for Polish: special acute accent kreska now available. To activate it, just select Polish as text language.
• Opentype SS02 feature added: stylistic alternate for /N/ glyph with all accented variants, included Polish kreska.
