Conversion PDF to HTML - new font set for every character


While converting PDF to HTML(see the attached file), characters are not recognized as UTF-8 characters, thus font representation is being generated. However, for each “character” in pdf, there is a separate font-family generated. Is this an expected behavior and is there a possibility to use one font family for the whole pdf content when characters are not identified as valid UTF-8 characters? asposeScreen.jpg (327.2 KB)

Below fragment of CSS file corresponding to a selected letter in asposeScreen.jpg file:

@font-face {
src:url(“xxx”) format(“woff”);
.stl_355 {
line-height: 1.046555em;
font-size: 0.86em;
font-family: “ASOCGB+CalibriRegular-Identity-H”, “Times New Roman”;
