English Quotation Marks Changing in Your Diary? Check Smart Punctuation and Test a Copy
If quotation marks in a diary entry change from straight marks (") to curly marks (“ ”), first find out where the change happens: the device keyboard, the diary app, or a later copy or export step. Check the setting for the device and app you actually use, change one control at a time, and test a short sample before editing older entries. Curly quotes are a typographic style; they do not by themselves mean that text has been lost.
What changed: the mark, the wording, or the punctuation?
Straight and curly quotation marks are different characters. A pair of straight double quotes looks like "like this"; curly double quotes have opening and closing forms: “like this.” Single quotation marks and apostrophes may also appear curly. The change can be intentional typography, while other automatic punctuation can change a double hyphen into an em dash or handle apostrophes differently.
Before opening settings, type a short test line in a new diary entry, such as She wrote "hello" and left. Look at the mark immediately after typing and again after you finish the word or sentence. Note whether the result is curly, whether its opening and closing directions make sense, and whether any other punctuation changed. If the marks stay straight while typing but change only after pasting, exporting, or opening the entry elsewhere, the keyboard setting may not be the cause.
Use the symptoms to locate the setting
Check the keyboard or system first when the same change happens while typing in several unrelated apps on one device. Check the diary app or editor when the change occurs only in that writing app. If it appears only after you paste text into another app or export the entry, compare the entry before and after that step; formatting or the receiving app may be involved. These are diagnostic clues, not guarantees: one app can apply its own rules on top of device-wide text behavior.
Also separate smart quotes from nearby features. Predictive text suggests words, autocorrect changes spelling, dictation may insert punctuation, and smart punctuation changes marks such as quotes and dashes. Switching off a broad autocorrect feature could affect other corrections without addressing the particular quote rule. Prefer a control specifically named for smart quotes, smart punctuation, or straight quotes when the app provides one.
On iPhone or iPad, check Smart Punctuation
Apple documents the iPhone setting as Settings > General > Keyboard > Smart Punctuation. Its guide explains that this setting affects quotation marks and double hyphens, applies in other apps used to enter text, and changes new text rather than marks already in the document. The control may therefore change more than quotes, so test dashes as well if your diary uses them. Apple: Format dashes and quotation marks in Numbers on iPhone
If your diary app has a separate quote or typography option, inspect that too, but do not assume it exists or has the same name across apps. The Apple path above is documented through its iPhone guide; the visible wording and availability can vary by software version and app. After changing a setting, create a fresh test entry rather than expecting existing text to convert automatically.
On a Mac, check the keyboard and the app
On Mac, Apple’s current guide places the system control at Apple menu > System Settings > Keyboard > Text Input > Edit, where you can turn Use smart quotes and dashes on or off and choose styles for double and single quotes. This control combines quotes and dashes, so consider both when testing. Apple also documents an app-level route: in a document, choose Edit > Substitutions > Show Substitutions and inspect Smart Quotes and Smart Dashes.

Apple notes that text replacements, smart quotes, and dashes are not available in every app. If the system control does not change what happens in your diary, look for the app’s own substitution or typography controls rather than repeatedly changing the system setting. For selected text or an existing document, Apple describes using the Substitutions panel to replace marks; make a copy before trying bulk replacement so you can preserve deliberate quote styles.
In Microsoft Word, check Word’s own AutoCorrect option
For desktop Word versions covered by Microsoft’s instructions, open File > Options > Proofing > AutoCorrect Options > AutoFormat As You Type, then find “Straight quotes” with “smart quotes” and clear it to stop Word converting newly typed marks. This is an application setting, separate from the Mac or phone keyboard control. Microsoft’s page covers Word for Microsoft 365 and several desktop versions; if you use another Word edition or a diary app that is not Word, verify its own controls.

If your entry has already been converted, changing this typing option is not a documented way to restore all earlier marks. Work on a duplicate entry, then use find and replace only when you understand which opening and closing forms you intend to change. A blanket replacement can erase meaningful distinctions or alter apostrophes along with dialogue quotes.
In Google Docs, distinguish substitutions from suggestions
Google’s desktop instructions place its controls at Tools > Preferences > Substitutions. There you can turn off selected substitutions or all automatic substitutions; Google says Docs autocorrect can handle quotes as well as other corrections. Its instructions say these settings are managed on a computer, not in the Docs Android or iPhone/iPad apps. Google: Manage Autocorrect in Google Docs
Do not confuse Smart Compose with quote substitution. Google describes Smart Compose as suggestions that appear while you write; accepting a suggestion is a separate action from automatic substitution. If quotes still change after adjusting a Docs substitution, retest in a fresh document and compare the same typed sample in another app to see whether the change is specific to Docs or happens earlier in text entry.

Keep intentional typography and verify copy or export
You may prefer curly quotes in ordinary prose and straight quotes in a passage where the literal character matters. If the editor offers a quote-style control, use it for the relevant text; if the device offers a broad toggle, switch it only as needed and check whether it also changes dashes. Do not replace every curly mark just because one code-like or quoted passage needs straight marks.
For a simple transfer check, duplicate a short entry containing both a normal sentence and a deliberate example of the mark style you want to preserve. Copy it into the destination you actually use, then inspect it there. If the diary app supports export, export a test copy and open that file in the intended reader. Compare the visible quote shapes and the surrounding words before applying the same route to a complete entry. If the characters look the same in both places, there may be no transfer issue to fix; if they differ, note the exact step where the change first appears and troubleshoot that app or export path.
A quick decision sequence
Type one short test sentence in a new entry and note when the marks change.
Repeat in another app on the same device. If both change while typing, check the device’s smart punctuation setting; if only the diary app changes them, inspect that app’s options.
If the difference appears only after transfer, compare the original with a pasted or exported test copy and focus on that transfer path.
Change one relevant setting, type a fresh test, and check both quotation marks and any affected dashes.
Keep a duplicate before converting existing entries, then inspect a real copy or export before relying on it.
The practical rule is to trace the change to the layer that produces it, then test that layer with a small entry. Device-wide punctuation, app substitutions, and transfer behavior are separate checks; the right setting depends on where the marks first change and which typography you want to keep.
