LibreOffice Math stellt griechische Buchstaben wie alpha, pi, theta nicht dar, obwohl: die Eingabe korrekt ist (alpha → α) OpenSymbol installiert und aktiv ist die Schriftart unter „Format → Schriftart → Mathematik“ korrekt auf OpenSymbol gesetzt ist Brüche (a over b) korrekt dargestellt werden sowohl Writer als auch Math betroffen sind der FontCache-Dienst aktiv ist (sc query FontCache → RUNNING) OpenOffice wurde deinstalliert LibreOffice wurde vollständig entfernt, inkl. Profil und Programmordner Neuinstallation durchgeführt /regserver ausgeführt Echtzeitschutz deaktiviert Schutzverlauf leer keine blockierten DLLs im Defender-Verlauf keine Verbesserung nach FontCache-Reset oder DISM/SFC Erwartetes Verhalten: alpha sollte als α dargestellt werden, pi als π, etc. Tatsächliches Verhalten: alpha bleibt ausgeschrieben, keine griechischen Buchstaben erscheinen. Brüche funktionieren, aber alle Symbolzeichen fehlen. Vermutung: Die StarMath-Engine wird geladen, aber die Symbolfont-Zuordnung schlägt fehl. Möglicherweise wird OpenSymbol nicht als Symbolfont erkannt oder die Font-Substitution blockiert.
<gloss> LibreOffice Math on Windows does not render Greek letters despite the OpenSymbol font being active. LibreOffice Math does not display Greek letters such as alpha, pi, and theta, even though: the input is correct (alpha → α) OpenSymbol is installed and active the font is correctly set to OpenSymbol under "Format → Font → Mathematics" fractions (a over b) are displayed correctly both Writer and Math are affected the FontCache service is active (sc query FontCache → RUNNING) OpenOffice has been uninstalled LibreOffice has been completely removed, including the profile and program folders a reinstallation has been performed /regserver has been executed real-time protection has been disabled the protection history is empty no blocked DLLs are listed in the Defender history no improvement after FontCache reset or DISM/SFC Expected behavior: alpha should be displayed as α, pi as π, etc. Actual behavior: alpha remains spelled out, no Greek letters appear. Fractions work, but all symbol characters are missing. Hypothesis: The StarMath engine is loaded, but the symbol font mapping fails. OpenSymbol may not be recognized as a symbol font, or font substitution is being blocked. </gloss>
Actually, isn't the actual StarMath syntax [1] for entry to precede each greek/special letter with '%' ? => WFM =-ref-= [1] https://books.libreoffice.org/en/MG252/MG25206-CommandReference.html#toc16
I’ve tested the issue in both Writer and standalone Math mode. The syntax is correct — I’m using standard StarMath input like alpha, pi, theta, and sin alpha = GK over H. Brackets, fractions, and layout commands like newline and quad work as expected. However, Greek letters do not render at all. Instead of showing symbols like α or π, the formula displays the codewords (alpha, pi) as plain text. This happens even though: OpenSymbol is installed and selected under Format → Fonts → Math The FontCache service is running (sc query FontCache = RUNNING) The system is clean: OpenOffice removed, LibreOffice reinstalled, profile reset No blocked DLLs or Defender interference /regserver has been executed The issue persists in both Writer and standalone Math I’ve also tried using font sans, nitalic, and other layout modifiers — no change. Brackets and fractions render correctly, but Greek symbols do not. This seems to be a reproducible issue on Windows, possibly related to how StarMath maps symbol fonts internally. Thanks again for looking into it — happy to provide more diagnostics or screenshots if needed.
I am not using any % comments in my formulas. The issue occurs even with a minimal input like alpha or pi alone.

Thank You! Danke, hab mich zu sehr auf die KI verlassen.... %alpha works!
