test: cover UTL_FILE NCHAR variants, FGETPOS and PUT_RAW - #2023
Conversation
utl_file.sql only exercised the plain FOPEN/PUT*/GET_LINE paths; the NCHAR variants (FOPEN_NCHAR, GET_LINE_NCHAR, PUT_LINE_NCHAR), FGETPOS and PUT_RAW had no regression coverage even though they are all implemented. Add tests that: - write and read back multibyte UTF8 lines through the NCHAR wrappers, checking round-trip equality; - report the file position with FGETPOS after writing; - write binary content containing an embedded NUL with PUT_RAW and check the resulting on-disk byte count. Testing: contrib/ivorysql_ora oracle-check (28/28).

Add a combining-character NCHAR round trip.
'héllo' contains precomposed é. It does not test a base character followed by a combining mark. Add a value such as U&'he\0301llo' to the write/read assertions. Otherwise, decomposed UTF-8 handling can regress while this test passes.

Closes #2022.
Adds regression coverage for UTL_FILE members that had none:
multibyte UTF8 lines (CJK + precomposed characters), checking
round-trip equality.
byte count via pg_read_binary_file().
No production code changes; test + expected output only.
Verified: make -C contrib/ivorysql_ora oracle-check -> 28/28.
