Limitations
- Java Properties.load(Reader) lexical semantics: separators, comments, continuation, escaped whitespace and four-hex-digit Unicode escapes. Text is already decoded Unicode, not ISO8859-1 byte loading. Last duplicate wins and duplicate names are reported; no interpolation or environment access.
- Text fields are limited to100,000 UTF16 units each and400,000 combined UTF8 bytes; file fields have their own displayed limits. Combined output is at most4MiB. Processing stops after30 seconds; tool-specific bounds may be tighter.
- Generated source is a downloadable result and is not executed here. Inspection does not establish remote behavior, trust or standards certification.
