c# - Why does the resource file format change after syncing from Perforce? -

i have active template library project used starting point writing dynamic link library (dll). has resource header: resource.h (this standard header file defines resource ids.)

it looks this:

//{{no_dependencies}} // microsoft visual c++ generated include file. // used myproject.rc // #define ids_projname                    100 #define idr_myproject                 101 #define idb_myprojectfilt             106 #define idr_myprojectfilt             107  // next default values new objects //  #ifdef apstudio_invoked #ifndef apstudio_readonly_symbols #define _aps_next_resource_value        201 #define _aps_next_command_value         32768 #define _aps_next_control_value         201 #define _aps_next_symed_value           108 #endif #endif 

now, after sync file depot using perforce (p4 client , not command-line), resource file changes this:

//{{no_dependencies}} ਍⼀⼀ 䴀椀挀爀漀猀漀昀琀 嘀椀猀甀愀氀 䌀⬀⬀ 最攀渀攀爀愀琀攀搀 椀渀挀氀甀搀攀 昀椀氀     攀⸀ഀഀ // used myproject.rc ਍⼀⼀ഀഀ #define ids_projname                    100 ਍⌀搀攀昀椀渀攀 䤀䐀刀开䄀唀䐀䤀伀匀倀䠀䔀刀䔀                 ㄀　㄀ഀഀ #define idb_myprojectfilt             106 ਍⌀搀攀昀椀渀攀 䤀䐀刀开䄀唀䐀䤀伀匀倀䠀䔀刀䔀䘀䤀䰀吀             ㄀　㜀ഀഀ  ਍⼀⼀ 一攀砀琀 搀攀昀愀甀氀琀 瘀愀氀甀攀猀 昀漀爀 渀攀眀 漀戀樀攀挀琀猀ഀഀ //  ਍⌀椀昀搀攀昀 䄀倀匀吀唀䐀䤀伀开䤀一嘀伀䬀䔀䐀ഀഀ #ifndef apstudio_readonly_symbols ਍⌀搀攀昀椀渀攀 开䄀倀匀开一䔀堀吀开刀䔀匀伀唀刀䌀䔀开嘀䄀䰀唀䔀        ㈀　㄀ഀഀ #define _aps_next_command_value         32768 ਍⌀搀攀昀椀渀攀 开䄀倀匀开一䔀堀吀开䌀伀一吀刀伀䰀开嘀䄀䰀唀䔀         ㈀　㄀ഀഀ #define _aps_next_symed_value           108 ਍⌀攀渀搀椀昀ഀഀ #endif ਍
