For other parameter > combinations Is that `ofDelimiter(delimiter)` ? src/java.base/share/classes/java/util/HexFormat.java line 408: > 406: * @param fromIndex the initial index of the range, inclusive > 407: * @param toIndex the final index of the range, exclusive. > 408: * @return a String formatting or null for non-single byte formatting `non-single byte delimiter`? src/java.base/share/classes/java/util/HexFormat.java line 853: > 851: */ > 852: public int fromHexDigit(int ch) { > 853: int value = Character.digit(ch, 16); Do we need to limit parsing the hex digit for only [0-9a-fA-F]? This would return `0` for other digits, say `fullwidth digit zero` (U+FF10) ------------- PR: https://git.openjdk.java.net/jdk/pull/482
