error: in __getitem__ return self.metrics[glyphName] KeyError: 'A'

Using this as a reference: https://groups.google.com/forum/#!topic/fonttools/ll4G3dOrDBc

I have this py script:

from fontTools.ttLib import TTFont
from fontTools.pens.svgPathPen import SVGPathPen

font = TTFont("./Center-Point-2026.ttf")
glyphSet = font.getGlyphSet()
svgpen = SVGPathPen(glyphSet)
glyph = glyphSet["A"]
glyph.draw(svgpen)
path = svgpen.getCommands()
print(path)

It is run against the a ttf I am developing.

Result:

C:\ae\adaept.com\ae-pytools>python .\ae-outglyph.py
Traceback (most recent call last):
  File ".\ae-outglyph.py", line 7, in <module>

GitHub will not allow me to attach the file.

What is the next step in this process?

Windows 10 x64

C:\ae\adaept.com\ae-pytools>python --version
Python 3.8.0

Using fonttools 4.2.4

You can attach the font as a zip file.

zipped font

Center-Point-2026.zip

Does your font contain a glyph named "A"?

[justvanrossum]

Does your font contain a glyph named "A"?

It doesn't, the font doesn't contain a proper post table with glyph names it seems.

[peterennis]

The font was created using glyphter.com

How do I make it have a "proper post table"?

[behdad]

See this for how to correctly get the glyph index for character "A":

fonttools/Lib/fontTools/pens/svgPathPen.py

Lines 216 to 217 in cdc5307

	g = cmap[ord(u)]
	glyph = glyphset[g]
