Suddha,

Assuming that it is indeed the precise same font that is being called up as "Helvetica" (same foundry (Adobe, Linotype, Bitstream, etc.), same font technology (OpenType, Type 1, TrueType), each character of the font will display identically, regardless of software used. The difference will be that, for example, Microsoft Word (an office tool, not a design or typographer tool), or Notepad does not display spacing the same way as InDesign will. This is a limitation of those applications. Adobe Reader accurately displays the information that it "reads". If the fonts in a specific document are embedded (that is, not fonts used by the host computer), then the file will be an exact typographic representation of the original document -- even if those fonts do not exist on that computer.

That said, for critical output, use PDFs with fonts embedded. And for the most accurate creation and display, prepare your files using design tools: InDesign, Illustrator, Photoshop, QuarkXPress, and NOT Word, Notepad or Wordpad. Designers need to be restrained with guns put to their heads to use any of the latter three for typography.

Also, use quality fonts from respected foundries, OpenType, Type 1, or TrueType.
