I added two TRACE calls myself to print the values of name & buffer
which gives:
0009:trace:dwrite:collection_find_family name=L"ARIAL"
and later:
0009:trace:dwrite:collection_find_family buffer=L"Arial"
Hi, Julius.
Patch is likely correct, but please add a test at the end of test_system_fontcollection() for Tahoma name to make sure it won't break in the future, and send it to wine-patches.
