Unicode Validator Features
When You Need a Unicode Validator
Text Migration
Validate text when migrating between encodings to ensure all characters are valid Bengali Unicode.
Database Validation
Check text before storing in databases to prevent encoding issues and data corruption.
API Development
Validate user input in APIs that accept Bangla text to ensure data quality.
Debugging
Identify invalid characters that cause display issues in applications and websites.
Understanding the Validation Result
The validator checks each character in your text against the Bengali Unicode block (U+0980–U+09FF). Characters in this range are valid Bangla — vowels, consonants, vowel signs, numerals, and special characters like danda (।) and hasanta (্). Characters outside this range are flagged with their Unicode code point and category.
Color coding helps you spot issues quickly. Green means valid Bengali. Yellow means non-Bangla (English letters, numbers, punctuation) — these are not errors, just not Bengali. Red means control characters or invalid code points that may cause display or processing problems. Use this tool before storing text in databases, sending via APIs, or publishing to catch encoding issues early.
Common Validation Problems & Fixes
| Problem | Cause | Fix |
|---|---|---|
| Valid Bangla text shows red or yellow characters | The text contains mixed content — English words, numbers, or punctuation alongside Bangla characters. | This is normal. Yellow characters are non-Bangla but valid. Only red characters (control or invalid code points) need attention. |
| Text displays correctly but validator flags characters | Some Unicode characters like zero-width joiners or combining marks may be flagged even though they render correctly. | Check the code point information. If the character is a legitimate Unicode combining mark or joiner, it is safe to keep. |
| Text from a database shows replacement characters (�) | The database connection or table collation does not use UTF-8 encoding, causing characters to be stored or retrieved incorrectly. | Ensure your database, table, and connection all use utf8mb4 character set. Re-import the text with correct encoding, then validate again. |
| Zero-width characters are flagged as control characters | Zero-width joiners (U+200D) and zero-width non-joiners (U+200C) are control characters used in Bangla for conjunct formation. | These are legitimate Unicode characters used in complex Bangla text. If they appear in conjuncts, they are correct. Remove them only if they appear unnecessarily. |
Frequently Asked Questions
What does the Unicode Validator check?
The validator checks each character in your text and determines if it falls within the valid Bengali Unicode range (U+0980–U+09FF). It also identifies control characters, non-Bangla characters, and other potential issues.
Why do I need to validate Unicode text?
Validation helps identify text that may display incorrectly or cause issues in databases, APIs, and applications. It is especially useful when migrating text between encodings or debugging character display problems.
What is the Bengali Unicode range?
Bengali characters are assigned code points from U+0980 to U+09FF in the Unicode standard. This includes all vowels, consonants, vowel signs, various signs, and Bengali digits (০-৯).
Can it detect mojibake or broken text?
The validator can identify characters outside the Bengali range, which may indicate encoding issues. For automatic mojibake repair, use the Broken Text Fixer tool.
What do the color codes mean?
Green characters are valid Bengali Unicode code points. Yellow characters are non-Bangla (Latin, digits, punctuation) — these are not errors, just not Bengali. Red characters are control characters or invalid code points that may cause display or processing issues.
Why does my valid Bangla text show non-Bangla characters?
Your text likely contains mixed content — Bangla text with embedded English words, numbers, URLs, or punctuation. These are not errors. The validator flags them so you can see the full character composition of your text.
Is this Unicode Validator free?
Yes, completely free. No registration, no daily limit, no character cap. All validation happens in your browser — there is no server-side processing. You can use it unlimited times for personal, educational, or commercial work.
Can I validate text with mixed Bangla and English content?
Yes. The validator handles mixed text naturally. Bangla characters are shown in green, English letters and numbers in yellow, and invalid or control characters in red. This color-coded approach lets you see exactly which parts of your text are Bangla, which are non-Bangla, and which may need attention.
