Steps to reproduce:

1. Configure Agent with old library PCRE2-10.30

   ./configure --prefix=$(pwd)/dist --enable-agent --with-libpcre2=/home/zabbix/workspace/downgraded_library/pcre2-10.30 -q

2. Create item with key: vfs.file.regexp["/home/zabbix/workspace/japan_jis_coding_2","error"]
3. Create file with encoding Shift_JIS (Japanese) and write some text like this:

   1. お母さんはフレームを洗っていました
   2. 良い天気
   3. error 4 こんにちは世界
   4. 良い天気
   5. お母さんはフレームを洗っていました
   6. error 3 hello
   7. お母さんはフレームを洗っていました

4. Go to Monitoring->Latest data and check

Result:
Line 6 is returned: 6. error 3 hello

Expected:
Line 3 should be returned, similar as it is returned for Agent2:

NOTE: in case, if key contains encoding vfs.file.regexp["/home/zabbix/workspace/japan_jis_coding_2","error",shift_jis], correct line is returned.
