When you use Anu Script Manager, the resulting text will not be in Unicode. That means you cannot effectively use that text on the web: (1) Users see it as junk characters unless they have necessary Anu fonts. Not everyone can get Anu fonts as they are not free. (2) Worst part is that Google and other search engines do not understand that your text is in Telugu and cannot show your website in their results for Telugu searches.
The best way is to use Unicode. There are few converters that convert text from Anu to Unicode:
- Harivillu’s Anu 2 Unicode Converter: You can upload a text file which is in Anu fonts and get the Unicode text back.
- Dynamic Font to Unicode Converter: You can paste the Anu text and get back text in Unicode.
- Unicode Converter: This can help convert many proprietary formats, in addition to Anu, into Unicode. If you are trying to convert text of the popular news papers that are non-Unicode you can try their Unicode Conversion Gateway instead. Both of the tools mentioned in first two bullets also use this library.
Please note that I have not tested these tools. The conversion can be lossy and accuracy might not be guaranteed.
