Description
Extract a reflective-response span by Unicode code-point indexes.
Adult-learning records allocate supplied participation, contact time, credits and optional requirements. A local fraction or eligibility predicate follows the chosen counting policy; it does not assess learning quality, recognize a qualification or establish contractual entitlement. Excluded and optional components can change the denominator.
Extract a reflective-response span by Unicode code-point indexes.
When to use this tool
Use Reflective Journal Prompt Response Span when checking the stated adult-learning participation, requirement, text or time convention.
How to use the tool and how it works
- Enter text, start, end. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read response, codePoints. Use the output convention below.
Extract a reflective-response span by Unicode code-point indexes. Require whole 0 <= start <= end <= code-point length; return the half-open slice and end-start count.1
Unicode code points and UTF-16 code units are different counting units. Neither alone measures user-perceived grapheme clusters or rendered text width.2
| Input field | Meaning and units | Accepted input |
|---|---|---|
| text | Text | Required. Text; maximum UTF-16 length 8192. |
| start | Zero-based Unicode code-point offset, inclusive. | Required. Safe integer; minimum 0. |
| end | Zero-based Unicode code-point offset, exclusive; not a UTF-16 position. | Required. Safe integer. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| response | Response | Required. Text; maximum UTF-16 length 8192. |
| codePoints | Code Points | Required. Safe integer. |

}Limitations and assumptions
- Indexes are not UTF-16 units or graphemes; no prompt recognition, reflection quality or learner meaning is inferred.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review the actual course plan, learner needs and governing credit/recognition policy with the responsible educational team for substantive decisions.
