Converting MCL Tamil to Unicode, in plain terms
MCL is another legacy Tamil format found in older documents and layout files, usually without any label that tells you what it is. If you have a file like that, this converter is the quick way out: paste the MCL text, run the conversion, and you get Unicode Tamil that behaves like any other text you type today.
How to recognise MCL text
A reliable first test is to paste a line into a notepad-style editor. Font-encoded Tamil shows up as a jumble of letters and signs instead of Tamil script. To give you something concrete, this converter stores தமிழ் in MCL as jkpH;, வணக்கம் as tzf;fk; and நன்றி as ed;wp. MCL text, like Kruti Tamil, contains invisible joiner characters, and our sample words matched Kruti's codes. The practical lesson is the same: copy and paste the source, never retype it, because the hidden characters matter.
The conversion itself
Select the MCL text in the original file and copy it, then paste it into the left box. Press Convert text and the Unicode Tamil appears on the right. Use Copy result to move it into your editor, or Download .txt to keep a plain-text file. For a long document, work through it in sections so you can compare each one with the original as you go.
What to proofread afterwards
Read the result against the original side by side. Vowel signs, pulli forms and joined consonants are the usual suspects when a word is slightly off. Fixing one stubborn word by hand in Unicode is usually quicker than hunting for a perfect match.
Who tends to need this
Typical cases are reviving an old document, merging older writing with new Tamil, or publishing archived material online. In each one the content is fine; it is the storage format that has aged. A single conversion usually solves it.
A few practical tips
Start small, compare, then scale up. Always copy from the original rather than retyping, because retyping can change the exact characters a legacy format expects. If a file combines more than one font, convert the pieces separately. Finally, clear the boxes before the next document.
Why Unicode is worth the effort
Unicode Tamil works the same everywhere. The same text opens in a browser, a spreadsheet and a chat window without anyone installing a font, and it can be searched and indexed. After converting, keep the Unicode version as the one you edit and leave the MCL original untouched as a backup.

MCL to Unicode: common questions
Why does MCL text contain hidden characters?
They are zero-width joiners that the format places between certain letters. They do not show on screen but they are part of the text the converter reads.
My text is MCL but the Kruti converter worked too. Is that a problem?
Not necessarily. The two agree for common words. For a long document, stick with the tool that matches the original and review rare letters.
Is the MCL font included with this tool?
The page can show a preview where one is supplied, but the converter itself does not depend on installing anything. It works with the character codes.
What about a scanned PDF or an image of Tamil text?
The converter works on text, not pictures. An image or scanned PDF has to go through text extraction or OCR before there is anything to convert.
How accurate is it?
It follows the mapping built into the page and handles ordinary Tamil well. No converter is perfect for every rare character, so a quick proofread is always worth it.
Is it safe to paste a private document here?
The converter works inside your browser, which is a good sign for privacy, but use your own judgement. If a document is truly sensitive, convert a small portion first and clear both boxes when you finish.
What causes a few wrong characters in an otherwise good conversion?
Rare letters, symbols and conjunct forms are where formats differ most. Convert the problem word on its own to see whether the issue is the source text or the format.
