Character at Index
Return the Unicode code point at a zero-based index.
Description
Return the Unicode code point at a zero-based index.
Character at Index is a focused tool for the following task. Return the Unicode code point at a zero-based index. It reports Character from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.
When to use Character at Index
Use this text operation when its stated character encoding, token boundaries, normalization, case handling, and output format match the surrounding workflow.
- Text
- Required string.
- Index
- Required integer.
The cited overview of Text processing supplies background for the terminology and domain context used by this tool.1
How Character at Index works
Return the Unicode code point at a zero-based index. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- Character
- Returned string.
Limitations and assumptions
- Unicode normalization, locale, grapheme clusters, malformed input, ambiguous syntax, and implementation-specific conventions can change text-processing results.
- Index must be at least 0.
- Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.
Alternative or Complementary approaches
Preserve the original text, test representative non-ASCII and malformed cases, and use a standards-aware parser or serializer when interoperability matters.
