EPAR table present in font?

Rationale:
The EPAR table is/was a way of expressing common licensing permissions
and restrictions in metadata; while almost nothing supported it, Dave
Crossland wonders that adding it to everything in Google Fonts could help
make it more popular.
More info is available at:

com.google.fonts/check/unitsperem_strict
Stricter unitsPerEm criteria for Google Fonts.
with Picon-Medium.otf
Rationale:
Even though the OpenType spec allows unitsPerEm to be any value between
16 and 16384, the Google Fonts project aims at a narrower set of
reasonable values.
The spec suggests usage of powers of two in order to get some performance
improvements on legacy renderers, so those values are acceptable.
But value of 500 or 1000 are also acceptable, with the added benefit that
it makes upm math easier for designers, while the performance hit of not
using a power of two is most likely negligible nowadays.
Another acceptable value is 2000. Since TT outlines are all integers (no
floats), then instances in a VF suffer rounding compromises, and
therefore a 1000 UPM is to small because it forces too many such
compromises.
Therefore 2000 is a good 'new VF standard', because 2000 is a simple 2x
conversion from existing fonts drawn on a 1000 UPM, and anyone who knows
what 10 units can do for 1000 UPM will know what 20 units does too.
Additionally, values above 2048 would result in filesize increases with
not much added benefit.
* WARN: Even though unitsPerEm (16) in this font is reasonable. It is strongly advised to consider changing it to 2000, since it will likely improve the quality of Variable Fonts by avoiding excessive rounding of coordinates on interpolations. [code: legacy-value]

com.google.fonts/check/name/familyname
Check name table: FONT_FAMILY_NAME entries.
with Picon-Medium.otf
Rationale:
Checks that the family name infered from the font filename matches the
string at nameID 1 (NAMEID_FONT_FAMILY_NAME) if it conforms to RIBBI and
otherwise checks that nameID 1 is the family name + the style name.
* FAIL: Entry [FONT_FAMILY_NAME(1):WINDOWS(3)] on the "name" table: Expected "Picon Medium" but got "Picon". [code: mismatch]

com.google.fonts/check/fontv
Check for font-v versioning.
with Picon-Medium.otf
Rationale:
The git sha1 tagging and dev/release features of Source Foundry `font-v`
tool are awesome and we would love to consider upstreaming the approach
into fontmake someday. For now we only emit a WARN if a given font does
not yet follow the experimental versioning style, but at some point we
may start enforcing it.
* INFO: Version string is: "Version 0.1"
The version string must ideally include a git commit hash and either a "dev" or a "release" suffix such as in the example below:
"Version 1.3; git-0d08353-release" [code: bad-format]
Result: INFO
com.google.fonts/check/ligature_carets
Are there caret positions declared for every ligature?
with Picon-Medium.otf
Rationale:
All ligatures in a font must have corresponding caret (text cursor)
positions defined in the GDEF table, otherwhise, users may experience
issues with caret rendering.
* WARN: GDEF table is missing, but it is mandatory to declare it on fonts that provide ligature glyphs because the caret (text cursor) positioning for each ligature must be provided in this table. [code: GDEF-missing]

com.google.fonts/check/ftxvalidator_is_available
Is the commandftxvalidator
(Apple Font Tool Suite) available?
Rationale:
There's no reasonable (and legal) way to run the command `ftxvalidator`
of the Apple Font Tool Suite on a non-macOS machine. I.e. on GNU+Linux or
Windows etc.
If Font Bakery is not running on an OSX machine, the machine running Font
Bakery could access `ftxvalidator` on OSX, e.g. via ssh or a remote
procedure call (rpc).
There's an ssh example implementation at:

com.google.fonts/check/mandatory_glyphs
Font contains .notdef as first glyph?
with Picon-Medium.otf
Rationale:
The OpenType specification v1.8.2 recommends that the first glyph is the
.notdef glyph without a codepoint assigned and with a drawing.
https://docs.microsoft.com/en-us/typography/opentype/spec/recom#glyph-0-the-notdef-glyph
Pre-v1.8, it was recommended that a font should also contain a .null, CR
and space glyph. This might have been relevant for applications on MacOS
9.
* WARN: Font should contain the .notdef glyph as the first glyph, it should not have a Unicode value assigned and should contain a drawing.

com.google.fonts/check/whitespace_glyphs

Result: FAIL
com.google.fonts/check/valid_glyphnames
Glyph names are all valid?
with Picon-Medium.otf
Rationale:
Microsoft's recommendations for OpenType Fonts states the following:
'NOTE: 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_.] and should
start with a letter, except the special glyph name ".notdef" which starts
with a period.'
https://docs.microsoft.com/en-us/typography/opentype/spec/recom#post-table
* FAIL: The following glyph names do not comply with naming conventions: -, 0, 1, 2, 3, 4, 5, 6, 7, 8 and 216 more.
A glyph name may be up to 31 characters in length, must be entirely comprised of characters from the following set: A-Z a-z 0-9 .(period) (underscore). and must not start with a digit or period. There are a few exceptions such as the special character ".notdef". The glyph names "twocents", "a1", and "" are all valid, while "2cents" and ".twocents" are not. [code: found-invalid-names]

com.google.fonts/check/dsig
Does the font have a DSIG table?
with Picon-Medium.otf
Rationale:
Microsoft Office 2013 and below products expect fonts to have a digital
signature declared in a DSIG table in order to implement OpenType
features. The EOL date for Microsoft Office 2013 products is 4/11/2023.
This issue does not impact Microsoft Office 2016 and above products.
This checks verifies that this signature is available in the font.
A fake signature is enough to address this issue. If needed, a dummy
table can be added to the font with the `gftools fix-dsig` script
available at https://github.com/googlefonts/gftools
Reference: https://github.com/googlefonts/fontbakery/issues/1845
* FAIL: This font lacks a digital signature (DSIG table). Some applications may require one (even if only a dummy placeholder) in order to work properly. You can add a DSIG table by running the `gftools fix-dsig` script. [code: lacks-signature]
