Combining Greek dialytika tonos is the Unicode character at U+0344 in Combining Diacritical Marks. Official name: COMBINING GREEK DIALYTIKA TONOS. It must follow a base letter (for example ι + U+0344 → ΐ).
Remember
Character ◌̈́ (combining; needs a base letter)
Unicode U+0344
Hex entity ̈́
Decimal ̈́
CSS escape \0344
Named entity (none)
Meaning dialytika (diaeresis) + tonos on Greek vowels
Not the same ΐ (precomposed) · U+0308+U+0301 · Greek koronis
Use ̈́ or ̈́ after a letter (no named form). Unicode discourages U+0344 for new text — prefer precomposed ΐ / ΰ or U+0308 then U+0301.
Built with Hex: ΐ
Built with Decimal: ΐ
Built with CSS (after ι): ΐ
Preferred combining: ΐ
Precomposed: ΐ
How It Works
1. Hex: write a base letter, then ̈́. Alone, U+0344 has no letter shape.
2. Decimal: same mark as 836 → ̈́ after the letter.
3. CSS: use \0344 in content after a letter in the string (here the letter is in the HTML, the mark is appended). Prefer four hex digits so the escape does not swallow the next character.
4. Preferred combining:̈ then ́ is the Unicode-recommended sequence instead of U+0344.
5. Precomposed:ΐ (U+0390) is usually best for normal text. NFC may turn ΐ into ΐ.
Pitfalls & Tips
Common mistakes when working with combining Greek dialytika tonos.
Base
Always use a base letter
U+0344 alone is invisible as a letter. Write ΐ, not a bare ̈́, when you want a visible glyph.
Unicode
U+0344 is discouraged
Unicode recommends U+0308 + U+0301 (or precomposed letters) instead of U+0344 for new documents.
NFC
Normalization may rewrite it
ι + U+0344 often becomes precomposed ΐ under NFC. Do not assume the code point stays U+0344 after processing.
Named?
No named entity
HTML5 does not define a name for U+0344. Use ̈́ or ̈́.
Spacing
Not the spacing dialytika tonos
U+0385 is a spacing Greek dialytika tonos character — different from combining U+0344.
CSS vs HTML
Do not mix escapes
\0344 belongs in CSS strings. ̈́ / ̈́ belong in HTML after a base letter.
Semicolon
End references
Always finish entities with ; — write ̈́, not ̈́.

Bottom line: Prefer precomposed ΐ / ΰ or U+0308+U+0301 for new text. Use ̈́ / ̈́ only when you need U+0344 explicitly, and \\0344 only inside CSS content.
