* NOTE: This test will generally fail if iconv() is not

*
* CPLRecode() will be tested using the test file containing
* a list of strings of the same text in different encoding. The
* string is non-ASCII to avoid trivial transformations. Test file
* has a simple binary format: a table of records, each record
* is 1024 bytes long. The first 24 bytes of each record contain
* encoding name (ASCII, zero padded), the last 1000 bytes contain
* encoded string, zero padded.
*
* NOTE 1: We can't use a test file in human readable text format
* here because of multiple different encodings including
* multibyte ones.
*
* The test file could be generated with the following simple shell
* script:
*
* #!/bin/sh
*
* # List of encodings to convert the test string into
* ENCODINGS="UTF-8 CP1251 KOI8-R UCS-2 UCS-2BE UCS-2LE UCS-4 UCS-4BE
* UCS-4LE UTF-16 UTF-32" # The test string itself in UTF-8 encoding. # This
* means "Improving GDAL internationalization." in Russian.

* seek=$((${RECORDSIZE}*${i}+${ENCSIZE})) of="recode-rus.dat" status=noxfer
* i=$((i+1))
* done
*
* NOTE 2: The test string is encoded with the special format
* "\uXXXX" sequences, so we able to paste it here.
*
* NOTE 3: We need a printf utility from the coreutils because of
* that. "env printf" should work avoiding the shell
* built-in.
*
* NOTE 4: "iconv" utility without the "-f" option will work with
* encoding read from the current locale.
*
* TODO: 1. Add more encodings maybe more test files.
* 2. Add test for CPLRecodeFromWChar()/CPLRecodeToWChar().
* 3. Test translation between each possible pair of
* encodings in file, not only into the UTF-8.
