featureParams for ‘cv01’-‘cv99’

Fields

feat_ui_label_name_id: NameId

The ‘name’ table name ID that specifies a string (or strings, for multiple languages) for a user-interface label for this feature. (May be NULL.)

feat_ui_tooltip_text_name_id: NameId

The ‘name’ table name ID that specifies a string (or strings, for multiple languages) that an application can use for tooltip text for this feature. (May be NULL.)

sample_text_name_id: NameId

The ‘name’ table name ID that specifies sample text that illustrates the effect of this feature. (May be NULL.)

num_named_parameters: u16

Number of named parameters. (May be zero.)

first_param_ui_label_name_id: NameId

The first ‘name’ table name ID used to specify strings for user-interface labels for the feature parameters. (Must be zero if numParameters is zero.)

character: Vec<Uint24>

The Unicode Scalar Value of the characters for which this feature provides glyph variants.
