Characters Listing tool
The Characters Listing tool scans translatable blocks and accumulates the set of distinct characters used, together with how often each one occurs. It also records the number of unique characters per block on the block's properties. The accumulated character set is typically used for font subsetting — determining which glyphs a font must provide for a given body of content.
By default both source and target text are scanned. When target text is included, a target locale must be supplied so the tool knows which translation to read.
Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
includeSource | boolean | true | Include source text in character listing |
includeTarget | boolean | true | Include target text in character listing |
Configure these parameters interactively and copy the flow-step YAML on the Tool Reference.
Examples
List source characters only
Build the character set from source text alone, for example before any translation exists.
includeSource: true includeTarget: false
Processing notes
Operates on translatable blocks; non-translatable structure passes through unchanged.
Frequencies are accumulated across all blocks; the per-block unique-character count is recorded on each block.
Limitations
At least one of source or target inclusion must be enabled.
Including target text requires a configured target locale.
