VARAK Why fonts change
A PDF often embeds only the letters it uses, called a subset. If you type a letter that is not in the subset, an editor must borrow a different font for it. Some editors instead cover the old text with a new text box in a default font.
What VARAK does
VARAK edits the page’s own text and keeps the original font whenever the document embeds it. If the font is not embedded, or lacks a character you type, VARAK uses the closest matching font and tells you instead of changing it silently.
How to check any editor
Edit one word, then zoom in. Compare the shape of the letters, the spacing and the colour. Type a character that appears nowhere else in the document, such as an accented letter, and see what happens.
Scanned pages
A scan is a picture, so there is no font to keep. Make Editable recognizes the text and sets it in a typeface matched to the scan so you can correct it.
