Inkscape does not see some of the fonts (Windows)

This was a bug in versions of Inkscape up to 0.43, caused by using an obsolete font cache. This cache is stored in the file called .fonts.cache-1. This file may be in your Windows folder, or in your Temp folder, or in "My documents" folder, or in the folder listed in the $HOME environment variable. Use file search by name to locate this file. Then simply delete this file and restart Inkscape; now it will see the new fonts.

If you are using 0.44 or 0.45 then OpenType/PostScript and Type1 fonts are not supported (this is a side-effect of the method used to fix the previous bug).

The issues with OpenType/PostScript and Type 1 fonts have been fixed in Inkscape 0.46.

Windows internally supports several different types of font:

* Bitmap and vector fonts (red 'A' icon) will never be supported by Inkscape because they are too simple to be useful for drawing. They're generally used on-screen only.
* TrueType fonts (blue/gray 'TT' icon) are fully supported
* Type1 fonts (red 'a' with shadow icon) are fully supported since 0.46
* OpenType fonts (green/black 'O' icon) come in two subtypes: TrueType outlines and PostScript outlines. To tell the difference, double click the font file from Control Panel, Fonts and read the second line of text. TrueType outlines are fully supported. PostScript outlines are fully supported since 0.46.
