It works fine if you convert the string to a char array and check each char, such as:

StringBuilder sb = new StringBuilder();
for (char curr : str.toCharArray()) {
    sb.append((SUPPORTED_EMOJI_SET.contains(curr)) ? convertCharToImgTag(curr) : curr);
}

where SUPPORTED_EMOJI_SET is just a set of chars, for example:

new HashSet() {{
    add('\ue415');
    add('\ue056');
    ...
}}

You could also do this with a regex but I believe the above would run faster.
