NHM Converter – Tamil font encoding converter

NHM Converter is a free-of-cost Tamil font encoding converter tool available for download from the makers of NHM writer.

Earlier, Suratha‘s Pongu Tamil was the only available tool.

The downloadble version is available for Windows and will be soon made available for Linux too.

Some of the features of NHM converter are:

1. Embedded fonts. You don’t need to install any fonts.

2. Speed of the conversion as conversion takes place at client side. We used NHM converter for the Tamil Wiktionary Automation project and it helped us convert font encoding of large MB files with ease.

3. Auto detect encoding

4. Extendability

5. Sometimes it will be helpful, if you want to type in a 8 -bit encoding without any font. (another usage of font embedding feature)

    thanks sir,

    another thing. how to create categories in tamil and in post comments place, how to change ‘leave a reply’ in tamil?

    like in Tamil Hindu.com

    how they change everything to tamil?

    1. If you have a blog like http://xyz.wordpress.com hosted at wordpress.com then go to /wp-admin/options-general.php and choose the blog language as Tamil. You can expect many of the blog interface to show in Tamil. But not guaranteed 100%.

      If you are hosting the site by your own like TamilHindu.com, then you need to edit the theme files manually. the theme files are located at /wp-content/themes/

    The NHM converter is really nice to use, but while converting Bamini to unicode I find that several characters are not translated correctly. Are you aware of how I can get around that?


  15. Hi Ravi!
    I couldn’t read Tamil font in web sites. It appears as question mark. Please solve this problem.

    Thanks with

    1. Hi rathan, can I know some websites you have problem with? Please let me know the operating system, browser you use too. In general you should be able to Unicode sites like Tamil Wikipedia ( http://ta.wikipedia.org ) without problem. Try installing Firefox 3.5+ and NHM writer. It should enable Tamil support.

    Hi RAVI

    I need to convert one microsoft word document into Malayalam…

    I need the software.


  25. நான் என் கணினியில் என்ஹெச்எம் கன்வர்ட்டரைப் பயன்படுத்தி வந்திருந்தேன். தற்சமயம் அது வேலை செய்யவில்லை. என்ஹெச்எம் வலைத்தளத்திலிருந்து புதிதாக கணினியிறக்கம் செய்யவும் இயலவில்லை. குறிப்பிட்ட வலைப்பக்கம் கிடைப்பதில்லை. (error:101 or so) அதில் ஏதாவது பிரச்சினையா அல்லது அது பணம் செலுத்த வேண்டிய சேவையாகிவிட்டதா?

  26. நன்றி. என் எச் எம் ஆனால் எனக்கும் ஒரு குறை நான் intel i3 processor use செய்கிறேன். அதில் ms word, excel உள்ளிட்டவைகளில் unicode நன்றாக செயல்படுகிறது ஆனால் photoshop ல் மட்டும் அது வேலை செய்வதில்லையே எதனால்?
    மேலும் இதற்கான பதிலை யாராவது தெரிந்தால் உடனே தெரியபடுத்தவும்……

  31. Hello Ravi –

    Even though the NHM software is basically designed for Tamil fonts, with its modularity and felxibility I am hoping that this should be possible.

    I have few word documents in malayalam non-unicode font. Is it possible to use NHM software to convert these to Unicode text? If so, how do I setup the mappings for the fonts?

    Hope I can get some answers…
