vb.net - .Net Windows Form Arabic Encoding issue at Runtime -

i created vb.net windows forms project under vs2008 , windows vista, when take code other pc having vs2015 , windows 10 faced encoding problem, application has arabic captions in it, visual studio able read captions when click start (f5) compile , run app see arabic text not encoded. knowing when took compiled version of app old pc , run in new pc behave expected , arabic texts displayed well, problem here on compile time of vs2015 under windows 10.

i searched around issue advises try open files code editor , use compatible encoding, don't have problem reading code content, problem when compiling code not encode arabic text.

the following code of frmwelcome.designer.vb

<global.microsoft.visualbasic.compilerservices.designergenerated()> _ partial class frmwelcome     inherits system.windows.forms.form      'form overrides dispose clean component list.     <system.diagnostics.debuggernonusercode()> _     protected overrides sub dispose(byval disposing boolean)         if disposing andalso components isnot nothing             components.dispose()         end if         mybase.dispose(disposing)     end sub      'required windows form designer     private components system.componentmodel.icontainer      'note: following procedure required windows form designer     'it can modified using windows form designer.

this expected screen:

and screen after compile:

please advise.

i managed solve problem, took me lot of time finish it.

the solution following:

1. open each file containing arabic visual basic editor encoding , choose arabic windows codepage 1256.
2. click on save , in save screen choose arrow on save button select save encoding , select utc-8.

it replace old file new 1 format, after finished files build solution , run , worked expected. (more 70 files , each of them 1 design , other code 140 files)

i hope experience problem can faced same issue.
