-------------------------------------
Ok, I'll go ahead and implement this then, thanks for your feedback.
> Glyphlist .properties are not ordered
> -------------------------------------
>
> Key: PDFBOX-2380
> URL: https://issues.apache.org/jira/browse/PDFBOX-2380
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.0
> Reporter: John Hewson
> Assignee: John Hewson
>
> Currently we use .properties files to load the glyph lists, however Java's
> Properties is not ordered (the properties are stored in a Hashtable) and so
> the glyphs are not read in the correct order.
> This results in incorrect encoding when calling GlyphList.unicodeToName(),
> because the Adobe glyph lists are ordered: the default mapping comes first,
> and auxiliary mappings follow it, for example:
> {code}
> space=0020
> spacehackarabic=0020
> {code}
> Currently in PDFBox, GlyphList.unicodeToName(0x20) returns "spacehackarabic",
> which is wrong, we always want the first entry in the glyph list.
> We need to move away from using .properties and instead just use Adobe's
> existing glyph list format, the only difference is that we switch {{=}} for
> {{;}}.
