Reason:
glib ini-function works only with UTF-8 in files. Bug raised if system charset not UTF-8.
Issue:
* recode to utf-8 before saving values of ini-params and
* recode from utf-8 after reading values of ini-params
Also fixed:
* if system codepage is not UTF-8, panelize named is always in utf-8 and seems as non-sense string.
* Recode panelize command names into system codepage from utf-8
* global variable utf8_display now initialized in any case (non-relative to ENABLE_CHARSET)
