-
--help-face -
Options for the font face
-
--help-subset-glyphset -
Subsetting glyph-set options
-
--help-subset-other -
Subsetting other options
-
--help-subset-flags -
Subsetting boolean options
-
--help-output -

Font-face options:
-
--font-file=filename -
Set font file-name
-
-y, --face-index=index -
Set face index (default: 0)
-
--face-loader=loader -
Set face loader to use (default: ot)
-
Supported face loaders are: ot/ft
-
--list-face-loaders -
List available face loaders and quit
Subset glyph-set option:
-g,--gids=list of glyph indices/ranges or *-
Specify glyph IDs or ranges to include in the subset. Use
--gids-=... to subtract codepoints from the current set.
-
--gids-file=filename -
Specify file to read glyph IDs or ranges from
--glyphs=list of glyph names or *-
Specify glyph names to include in the subset. Use
--glyphs-=... to subtract glyphs from the current set.
-
--glyphs-file=filename -
Specify file to read glyph names from
-
-t, --text=string -
Specify text to include in the subset. Use
--text-=... to subtract codepoints from the current set.
-
--text-file=filename -
Specify file to read text from
-u,--unicodes=list of hex numbers/ranges or *-
Specify Unicode codepoints or ranges to include in the subset. Use * to include all codepoints.
--unicodes-=... can be used to subtract codepoints from the current set. For example:--unicodes=*--unicodes-=41,42,43 would create a subset with all codepoints except for 41, 42, 43.
-
--unicodes-file=filename -
Specify file to read Unicode codepoints or ranges from
Subset other option:
--gid-map=List of pairs old_gid1:new_gid1,old_gid2:new_gid2,...-
Specify a glyph mapping to use, any unmapped gids will be automatically assigned.
--name-IDs=list of int numbers or *-
Subset specified nameids. Use
--name-IDs-=... to subtract from the current set.
--name-languages=list of int numbers or *-
Subset nameRecords with specified language IDs. Use
--name-languages-=... to subtract from the current set.
--layout-features=list of string table tags or *-
Specify set of layout feature tags that will be preserved. Use
--layout-features-=... to subtract from the current set.
--layout-scripts=list of string table tags or *-
Specify set of layout script tags that will be preserved. Use
--layout-scripts-=... to subtract from the current set.
--drop-tables=list of string table tags or *-
Drop the specified tables. Use
--drop-tables-=... to subtract from the current set.
--variations=list of comma separated axis-locations.-
(Partially|Fully) Instantiate a variable font. A location consists of the tag of a variation axis, followed by '=', followed by a number or the literal string 'drop'. For example:
--variations="wdth=100 wght=200" or--variations="wdth=drop"
Subset boolean option:
-
--keep-everything -
Keep everything by default. Options after this can override the operation.
-
--no-hinting -
Whether to drop hints
-
--retain-gids -
If set don't renumber glyph ids in the subset.
-
--desubroutinize -
Remove CFF/CFF2 use of subroutines
-
--downgrade-cff2 -
Convert instantiated variable fonts from CFF2 to CFF1
-
--cff-identity-charset -
Emit identity CFF charset (CID = new GID) for CID-keyed CFF
-
--name-legacy -
Keep legacy (non-Unicode) 'name' table entries
-
--set-overlaps-flag -
Set the overlaps flag on each glyph.
-
--notdef-outline -
Keep the outline of '.notdef' glyph
-
--no-prune-unicode-ranges -
Don't change the 'OS/2 ulUnicodeRange*' bits.
-
--no-layout-closure -
Don't perform glyph closure for layout substitution (GSUB).
-
--no-bidi-closure -
Don't perform bidi closure (adding mirrored variants) for input codepoints.
-
--glyph-names -
Keep PS glyph names in TT-flavored fonts.
-
--passthrough-tables -
Do not drop tables that the tool does not know how to subset.
-
--preprocess -
If set preprocesses the face with the add accelerator option before actually subsetting.
-
--optimize -
Perform IUP delta optimization on the resulting gvar table's deltas
Output destination & format options:
-
-o, --output-file=filename -
Set output file-name (default: stdout)
Application Options:
-
--version -
Show version numbers
-
-n, --num-iterations=N -
Run subsetter N times (default: 1)
