Capital i-İ (Turkish) doesnot work

in 5.1 win7 other Turkish characters are fine. both capital and lower case other characters work fine but İ capital i somehow does’nt work. is there a solution for thiskind of problem. This is the first time I’musing libreoffice

Some work was done last months:

tdf#99587 - make rsc work in tr_TR.UTF-8 locale.

Looks it should be in 5.2 version
