# Known Problems

1. Version 4.00+ itrans can handle simple comments in the transliterated text portion of the input file. % character begins a comment, the end-of-line terminates a comment. Handling of comments is not fully coded yet, and has some problems in that the % always starts a comment, only exception being when % is preceded by a backslash (`\`). Of course, there are many other instances where % should not begin a comment, those are ignored for now. (And may be ignored for ever, recognizing comments correctly would require too much effort.)

2. In the TEX interface, characters with any non-zero Y offset are not correctly printed in some cases, when the PostScript font Devnac is used. One such case is the da-ra ligature, words such as draaviiDa (). (Another case is the ha-u form , see how it is handled in the sample input file nehru.itx.) Note that it is only in certain cases that the word is printed incorrectly, in most cases it is handled correctly. Usually, when the word appears near the end of the line, TEX (or dvips, but that sounds improbable) inserts a kern (a glue factor ?) just before the character with a non-zero Y offset, and the word appears squashed up or pulled apart at that point. Have no remedy for this, only workaround is to force a line break before the problem word, it usually sets everything right.

   I have never encountered this problem when using Frans Velthuis's Devnag font with the itrans package, therefore this problem is probably related to the use of PostScript fonts in TEX. If you do notice this problem with the Devnag font too, please let me know.
