On some web pages I get emojiis instead of ‘normal’ characters / symbols

I have the iPad 4th generation which I’ve had for about 6 months, running software version 14.7. When I go into some web pages, Tripadvisor for instance I get emojiis instead of standard characters or symbols, instead of the calendar symbol next to where you’d change the date I get a tennis ball emojii and in the rating section instead of their green dots I get emojiis of fax machines ! This is the same all over the page, it’s not the website as I tried exactly the same on my husband’s iPad and his shows the normal characters. I don’t want to remove emojiis completely from my iPad just where it appears on some webpages. Does anyone get the same thing or know how to correct it please ?
