Currently, I am facing the challenge of showing a negative number in an HTML page with rtl direction.
Despite using direction: ltr, the label does not display correctly.
To demonstrate the issue, I have created a jsFiddle showcasing the reverse scenario (attempting to display from right to left).
To solve this issue, simply include unicode-bidi: embed; in your CSS code. This should resolve the problem - check out the updated Fiddle for reference.

When dealing with the CSS property direction: ltr, it may be confusing why the minus sign is not positioned to the left of a number. This is because the surrounding characters dictate the directionality, with right-to-left characters influencing the placement of "neutral" characters like digits and the minus sign. The direction property primarily impacts the layout of boxes rather than the writing direction of text.
For example:
<p>א <label id="ProfitShk" class="labelVal">-9 ₪</label> ת
<p>a <label id="ProfitShk" class="labelVal">-9 ₪</label> b
In the first case, the hyphen aligns to the right of the digit 9 due to the surrounding right-to-left text. In the second case, the opposite occurs as the surrounding characters are left-to-right Latin letters.
To address this issue, various solutions can be considered:
unicode-bidi: bidi-override in CSS along with direction to ignore inherent directionality and enforce the specified order.unicode-bidi: embed in CSS along with direction to create a directional island where the surrounding text does not impact the directionality, allowing the direction property to dictate text direction.<bdo> element in HTML with the dir attribute as an alternative to method 2, addressing fundamental directionality issues without stylistic considerations.‎ and ‏ respectively, ensuring proper directionality of "neutral" character strings.While these approaches provide solutions, employing <bdo> is recommended for optimal results. When setting directionality, it is crucial to confine it to the smallest relevant string, such as -9 in the example:
<p>א <label id="ProfitShk" class="labelVal"><bdo dir="ltr">-9</bdo> ₪</label> ת
Furthermore, using the Unicode minus sign “−” U+2212 MINUS SIGN (represented as − in HTML) for the minus sign is ideal, though it does not directly impact the directionality issue.
Adding onto Henrik's response, I suggest incorporating a LRM control character before the minus sign as shown below:
<label id="ProfitShk" class="labelVal">‎-9 ₪</label>
By doing this, the minus sign will be positioned before the 9, which is likely what you intended.
