A family of Microsoft relational database management systems designed for ease of use.
The characters shown are the result of text being rendered with the wrong encoding or with missing/incorrect fonts, so the stored text is actually correct but the glyphs that Access (or Windows) chooses to display are wrong. This is why copying the text out of the control shows the expected string “ASTM A108, ASTM A29” even though the form displays “ÐÈÉÊÃÐA,ÃBÐÈÉÊÃAC”.
In similar cases, square boxes or unexpected symbols appear when an app cannot render certain characters with the fonts or encoding it is using. On Windows 10 this typically happens when:
- The app or control is not using proper font fallback and the needed glyphs are not available in the current font.
- The text is interpreted with the wrong encoding or locale settings, so bytes are mapped to the wrong characters.
To mitigate in Access on Windows:
- Ensure the form controls use a standard, fully supported font (for example, a common Windows 10 UI font) and not a specialty or custom font that might be missing or partially installed.
- Avoid copying data into the table or form from sources that may use different encodings or special characters unless pasted as plain text.
- If the issue appears only intermittently, close and reopen Access so the form reloads fonts and layout; if it persists, recreate the affected control and rebind it to the same field so any corrupted control-level formatting is removed.
- If this is seen across multiple apps, review Windows language/locale and font settings, and install any missing optional font packs required for the languages in use.
These steps address the underlying display/encoding problem without changing the actual stored data, which is already correct.
