App allows '÷×' symbols in legal name even though error states that 'Name can only include letters'

[Pluto0104]

I have read the CLA Document and I hereby sign the CLA

Details

The application currently allows the use of the symbols ÷ and × in the legal name field, which is not intended. This behavior is caused by the ALPHABETIC_AND_LATIN_CHARS regular expression in the codebase. This regular expression includes the Latin character range À-ÿ, which unintentionally includes the × and ÷ symbols.

To address this issue, I suggest modifying the following constants:

ALPHABETIC_AND_LATIN_CHARS: /^[\p{Script=Latin} ]*$/u
NON_ALPHABETIC_AND_NON_LATIN_CHARS: /[^\p{Script=Latin}]/gu

The updated ALPHABETIC_AND_LATIN_CHARS regular expression matches any string that consists of one or more characters from the Latin script. The NON_ALPHABETIC_AND_NON_LATIN_CHARS regular expression matches any character that is not a Latin character.

PROPOSAL: #24508 (comment)

Tests

1. Go to Settings > Profile > Personal details > Legal name.
2. In either the First name or Last name field, input the characters ÷ or ×. If you are using a web browser, you can copy and paste the characters from another source. For mobile devices, switch the keyboard to the number keypad to access these symbols.
3. Once you have entered the characters, click on the Save button.
4. Verify that the app does not allow you to save the data, indicating that the use of ÷ and × symbols in the legal name field is not permitted.

• Verify that no errors appear in the JS console

Offline tests

1. Go to Settings > Profile > Personal details > Legal name.
2. In either the First name or Last name field, input the characters ÷ or ×. If you are using a web browser, you can copy and paste the characters from another source. For mobile devices, switch the keyboard to the number keypad to access these symbols.
3. Once you have entered the characters, click on the Save button.
4. Verify that the app does not allow you to save the data, indicating that the use of ÷ and × symbols in the legal name field is not permitted.

QA Steps

1. Go to Settings > Profile > Personal details > Legal name.
2. In either the First name or Last name field, input the characters ÷ or ×. If you are using a web browser, you can copy and paste the characters from another source. For mobile devices, switch the keyboard to the number keypad to access these symbols.
3. Once you have entered the characters, click on the Save button.
4. Verify that the app does not allow you to save the data, indicating that the use of '÷' and '×' symbols in the legal name field is not permitted.

  • Android / native
  • Android / Chrome
  • iOS / native
  • iOS / Safari

  • MacOS / Desktop
• I verified there are no console errors (if there's a console error not related to the PR, report it or open an issue for it to be fixed)
• I followed proper code patterns (see Reviewing the code)
  • I verified that any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick)

  • I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
  • I verified any copy / text that was added to the app is grammatically correct in English.

  • A similar component doesn't exist in the codebase
  • All props are defined accurately and each prop has a /** comment above it */
  • The file is named correctly
  • The component has a clear name that is non-ambiguous and the purpose of the component can be inferred from the name alone
  • The only data being stored in the state is data necessary for rendering and nothing else
  • If we are not using the full Onyx data that we loaded, I've added the proper selector in order to ensure the component only re-renders when the data it is using changes
  • For Class Components, any internal methods passed to components event handlers are bound to this properly so there are no scoping issues (i.e. for onClick={this.submit} the method this.submit should be bound to this in the constructor)
  • Any internal methods bound to this are necessary to be bound (i.e. avoid this.submit = this.submit.bind(this); if this.submit is never passed to a component event handler like onClick)
  • All JSX used for rendering exists in the render method
  • The component has the minimum amount of code necessary for its purpose, and it is broken down into smaller components in order to separate concerns and functions
• If any new file was added I verified that:
  • The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
• If a new CSS style is added I verified that:
  • A similar style doesn't already exist
  • The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(themeColors.componentBG))
• If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
• If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
• If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
• If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
• If a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.
• If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.
• I have checked off every checkbox in the PR author checklist, including those that don't apply to this PR.

Hi @robertKozik, Thank you for your time.
If we only want to validate standard Latin letters without considering any combining marks, \p{Script=Latin} would be sufficient. but if we want to validate Latin characters and their possible combinations with combining marks (diacritics), then \p{Script=Latin}\p{M} would be more suitable.

Considering the current code is using \p{Script=Latin} for only standard Latin letters, if we want to include the validation of Latin characters with combining marks, we should indeed add \p{M} to the pattern.

[robertKozik]

@Pluto0104 Do we allow them until now?

[Pluto0104]

@Pluto0104 Do we allow them until now?

@robertKozik No, we only allowed ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõöøùúûüýþÿ and ÷×. - À-ÿ until now. These characters are included in Script=Latin

[Pluto0104]

@robertKozik so should we add them \p{M} to the pattern? If so, I can make the necessary changes and submit the pull request within 10 minutes.

[robertKozik]

Sorry I went OOO for today, I'll come back to this PR tommorow. But basically I would stick to the behaviour we have until now

@robertKozik No, we only allowed ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõöøùúûüýþÿ and ÷×. - À-ÿ until now. These characters are included in Script=Latin

So i believe tour current changes are sufficient right?

[Pluto0104]

@robertKozik that's correct. thank you for your time.

I reported a similar bug a month ago. It was about using numbers in legal names. The error says 'only letters'. Is it okay if it includes numbers?

[madmax330]

This caused a regression: https://expensify.slack.com/archives/C049HHMV9SM/p1691943529706359

[robertKozik]

@madmax330 the issue from slack is 11 days old - this PR was deployed on staging 4 hours ago. Are you sure this one caused it?

[madmax330]

Good point, maybe this one? https://github.com/Expensify/App/pull/23650/files although not sure how that would cause a regression

[robertKozik]

I'm not sure tbh, last change before the pull you provided is actually from the PR which fixes the Spanish characters.

But I think we have never supported non-latin chars (only latin with diacritics - for example the Spanish ones are working fine) - the video from the slack issue uses the Chinese characters which are not supported in regex even before the PR.

You're right - @robertKozik.

Even before this PR, we have never supported other characters except Latin and alphabetic ones. And current PR actually removed non-Latin characters such as ÷ and × from previous regex. So I don't think this causes a regression.

[madmax330]

Cool, thanks guys
