Converting Asian Fonts Text to Latin Fonts

[suchiate]

Hey guys,

I just received a file from Japan and the document has two types of fonts
together asian font and latin fonts (Times). I want to convert all the fonts
to Times but not able to do it. How can I convert the Asian Text to Latin
Text? I have tried highlighting them and changing them to Times which doesn't
work and also tried copying it to notepad and copying it back.

Please help.
Thanks.
