**Describe the bug** The following functions raise Poco::SyntaxException exceptions: Poco::NumberParser::tryParseHex, ... (all tryParse* ?) **Expected behavior** tryParse* functions does not raise any exceptions. **Logs** NumericString.h : strToInt ``` if (*pStr == thSep) { if (base == 10) continue; throw Poco::SyntaxException("strToInt: thousand separators only allowed for base 10"); } ``` **Please add relevant environment information:** - OS: Windows11 - POCO Version: 1.12, or later (The problem does not occur in version 1.9.)
