Glyph names in a `post' table must not contain spaces, since they are intended to be used as PostScript entities. A PostScript program uses spaces to separate tokens. >From the MS recommendations for OpenType fonts, section `post' table: https://www.microsoft.com/typography/otspec/recom.htm The PostScript glyph name must be no longer than 31 characters, include only uppercase or lowercase English letters, European digits, the period or the underscore, i.e. from the set [A-Za-z0-9_.] [...] Werner
