| 10:03 | New function fossil_utf8_to_filename, such that fossil_unicode_to_utf8/fossil_utf8_to_unicode/fossil_unicode_free are not used on UNIX/MAC any more: On UNIX those 3 functions were only no-ops, but this allows to re-implement then for real unicode <-> utf-8 conversions. There is an "#ifdef _WIN32" around those 3 functions and 2 more (fossil_mbcs_to... Leaf check-in: cc3976fd30 user: jan.nijtmans tags: fossil_utf8_to_filename | |
